Chapter 10, Problem 10.28E
Estimating a cost function, high-low method. Lacy Dallas is examining customer-service costs in the southern region of Camilla Products. Camilla Products has more than 200 separate electrical products that are sold with a 6-month guarantee of full repair or replacement with a new product. When a product is returned by a customer a service report is prepared. This service report includes details of the problem and the time and cost of resolving the problem. Weekly data for the most recent 8-week period are as follows:
| Week | Customer-Service Department Costs | Number of Service Reports |
| 1 | $13,300 | 185 |
| 2 | 20,500 | 285 |

Use the following information for Problems 3-60 and 3-61: Farnsworth Company has gathered data on its overhead activities and associated costs for the past 10 months. Tracy Heppler, a member of the controllers department, has convinced management that overhead costs can be better estimated and controlled if the fixed and variable components of each overhead activity are known. One such activity is receiving raw materials (unloading incoming goods, counting goods, and inspecting goods), which she believes is driven by the number of receiving orders. Ten months of data have been gathered for the receiving activity and are as follows:arrow_forwardUsing the information in the previous exercises about Marleys Manufacturing, determine the operating income for department B, assuming department A sold department B 1,000 units during the month and department A reduces the selling price to the market price.arrow_forwardCorazon Manufacturing Company has a purchasing department staffed by five purchasing agents.

- Ventana Window and Wall Treatments Company provides draperies, shades, and various window treatments. Ventana works with the customer to design the appropriate window treatment, places the order, and installs the finished product. Direct materials and direct labor costs are easy to trace to the jobs. Ventanas income statement for last year is as follows: Ventana wants to find a markup on cost of goods sold that will allow them to earn about the same amount of profit on each job as was earned last year. Required: 1. What is the markup on cost of goods sold (COGS) that will maintain the same profit as last year? (Round the percentage to two significant digits.) 2. A customer orders draperies and shades for a remodeling job. The job will have the following costs: What is the price that Ventana will quote given the markup percentage calculated in Requirement 1? (Round the price to the nearest dollar.) 3. What if Ventana wants to calculate a markup on direct materials cost, since it is the largest cost of doing business? What is the markup on direct materials cost that will maintain the same profit as last year? (Round the percentage to two significant digits.) What is the bid price Ventana will use for the job given in Requirement 2 if the markup percentage is calculated on the basis of direct materials cost?

The management has identified the following overhead costs and related cost drivers for the coming year. The following were incurred in manufacturing two of their cell phones, Bubble and Burst, during the first quarter. REQUIREMENT Review the worksheet called ABC that follows these requirements. You have been asked to determine the cost of each product using an activity-based cost system. Note that the problem information is already entered into the Data Section of the ABC worksheet.arrow_forwardJohnson Filtration. Inc., provides maintenance service for water filtration systems throughout southern Florida. Customers contact Johnson with requests for maintenance service on their water filtration systems. To estimate the service time and the service cost. Johnson’s managers want to predict the repair time necessary for each maintenance request. Hence, repair time in hours is the dependent variable. Repair time is believed to be related to three factors: the number of months since the last maintenance service, the type of repair problem (mechanical or electrical), and the repairperson who performs the repair (Donna Newton or Bob Jones). Data for a sample of 10 service calls are reported in the following table: Develop the simple linear regression equation to predict repair time given the number of months since the last maintenance service, and use the results to test the hypothesis that no relationship exists between repair time and the number of months since the last maintenance service at the 0.05 level of significance. What is the interpretation of this relationship? What does the coefficient of determination tell you about this model? Using the simple linear regression model developed in part (a), calculate the predicted repair time and residual for each of the 10 repairs in the data. Sort the data in ascending order by value of the residual. Do you see any pattern in the residuals for the two types of repair? Do you see any pattern in the residuals for the two repairpersons? Do these results suggest any potential modifications to your simple linear regression model? Now create a scatter chart with months since last service on the x-axis and repair time in hours on the y-axis for which the points representing electrical and mechanical repairs are shown in different shapes and/or colors. Create a similar scatter chart of months since last service and repair time in hours for which the points representing repairs by Bob Jones and Donna Newton are shown in different shapes and/or colors. Do these charts and the results of your residual analysis suggest the same potential modifications to your simple linear regression model? Create a new dummy variable that is equal to zero if the type of repair is mechanical and one if the type of repair is electrical. Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service and the type of repair. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Create a new dummy variable that is equal to zero if the repairperson is Bob Jones and one if the repairperson is Donna Newton. Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service and the repairperson. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service, the type of repair, and the repairperson. What are the interpretations of the estimated regression parameters? What does the coefficient of determination tell you about this model? Which of these models would you use? Why?arrow_forward
- Baker, Inc., supplies wheels for a large bicycle manufacturing company. The bicycle company has recently requested that Baker decrease its delivery time. Baker made a commitment to reduce the lead time for delivery from seven days to one day. To help achieve this goal, engineering and production workers had made the commitment to reduce time for the setup activity (other activities such as moving materials and rework were also being examined simultaneously). Current setup times were 12 hours. Setup cost was 600 per setup hour. For the first quarter, engineering developed a new process design that it believed would reduce the setup time from 12 hours to nine hours. After implementing the design, the actual setup time dropped from 12 hours to seven hours. Engineering believed the actual reduction was sustainable. In the second quarter, production workers suggested a new setup procedure. Engineering gave the suggestion a positive evaluation, and they projected that the new approach would save an additional six hours of setup time. Setup labor was trained to perform the new setup procedures. The actual reduction in setup time based on the suggested changes was four hours. Required: 1. What kaizen setup standard would be used at the beginning of each quarter? 2. Describe the kaizen subcycle using the two quarters of data provided by Baker. 3. Describe the maintenance subcycle for setups using the two quarters of data provided by Baker. 4. How much non-value-added cost was eliminated by the end of two quarters? Discuss the role of kaizen costing in activity-based management. 5. Explain why kaizen costing is compatible with activity-based responsibility accounting while standard costing is compatible with financial-based responsibility accounting.arrow_forwardSuppose that Kicker had the following sales and cost experience (in thousands of dollars) for May of the current year and for May of the prior year: In May of the prior year, Kicker started an intensive quality program designed to enable it to build original equipment manufacture (OEM) speaker systems for a major automobile company. The program was housed in research and development. In the beginning of the current year, Kickers accounting department exercised tighter control over sales commissions, ensuring that no dubious (e.g., double) payments were made. The increased sales in the current year required additional warehouse space that Kicker rented in town. (Round ratios to four decimal places. Round sales dollars computations to the nearest dollar.) Required: 1. Calculate the contribution margin ratio for May of both years. 2. Calculate the break-even point in sales dollars for both years. 3. Calculate the margin of safety in sales dollars for both years. 4. CONCEPTUAL CONNECTION Analyze the differences shown by your calculations in Requirements 1, 2, and 3.arrow_forwardMott Company recently implemented a JIT manufacturing system. After one year of operation, Heidi Burrows, president of the company, wanted to compare product cost under the JIT system with product cost under the old system. Motts two products are weed eaters and lawn edgers. The unit prime costs under the old system are as follows: Under the old manufacturing system, the company operated three service centers and two production departments. Overhead was applied using departmental overhead rates. The direct overhead costs associated with each department for the year preceding the installation of JIT are as follows: Under the old system, the overhead costs of the service departments were allocated directly to the producing departments and then to the products passing through them. (Both products passed through each producing department.) The overhead rate for the Machining Department was based on machine hours, and the overhead rate for assembly was based on direct labor hours. During the last year of operations for the old system, the Machining Department used 80,000 machine hours, and the Assembly Department used 20,000 direct labor hours. Each weed eater required 1.0 machine hour in Machining and 0.25 direct labor hour in Assembly. Each lawn edger required 2.0 machine hours in Machining and 0.5 hour in Assembly. Bases for allocation of the service costs are as follows: Upon implementing JIT, a manufacturing cell for each product was created to replace the departmental structure. Each cell occupied 40,000 square feet. Maintenance and materials handling were both decentralized to the cell level. Essentially, cell workers were trained to operate the machines in each cell, assemble the components, maintain the machines, and move the partially completed units from one point to the next within the cell. During the first year of the JIT system, the company produced and sold 20,000 weed eaters and 30,000 lawn edgers. This output was identical to that for the last year of operations under the old system. The following costs have been assigned to the manufacturing cells: Required: 1. Compute the unit cost for each product under the old manufacturing system. 2. Compute the unit cost for each product under the JIT system. 3. Which of the unit costs is more accurate? Explain. Include in your explanation a discussion of how the computational approaches differ. 4. Calculate the decrease in overhead costs under JIT, and provide some possible reasons that explain the decrease.arrow_forward
- Jean and Tom Perritz own and manage Happy Home Helpers. Inc. (HHH), a house-cleaning service. Each cleaning (cleaning one house one time) takes a team of three house cleaners about 1.5 hours. On average, HHH completes about 15,000 cleanings per year. The following total costs are associated with the total cleanings: Next year, HHH expects to purchase 25,600 of direct materials. Projected beginning and ending inventories for direct materials are as follows: There is no work-in-process inventory and no finished goods inventory; in other words, a cleaning is started and completed on the same day. Required: 1. Prepare a statement of cost of services sold in good form. 2. How does this cost of services sold statement differ from the cost of goods sold statement for a manufacturing firm?arrow_forwardThe expected costs for the Maintenance Department of Stazler, Inc., for the coming year include: Fixed costs (salaries, tools): 64,900 per year Variable costs (supplies): 1.35 per maintenance hour Estimated usage by: Actual usage by: Required: 1. Calculate a single charging rate for the Maintenance Department. 2. Use this rate to assign the costs of the Maintenance Department to the user departments based on actual usage. Calculate the total amount charged for maintenance for the year. 3. What if the Assembly Department used 4,000 maintenance hours in the year? How much would have been charged out to the three departments?arrow_forwardMantenga Company provides routine maintenance services for heavy moving and transportation vehicles. Although the vehicles vary, the maintenance services provided follow a fairly standard pattern. Recently, a potential customer has approached the company, requesting a new maintenance service for a radically different type of vehicle. New servicing equipment and some new labor skills will be needed to provide the maintenance service. The customer is placing an initial order to service 150 vehicles and has indicated that if the service is satisfactory, several additional orders of the same size will be placed every 3 months over the next 3 to 5 years. Mantenga uses a standard costing system and wants to develop a set of standards for the new vehicle. The usage standards for direct materials such as oil, lubricants, and transmission fluids were easily established. The usage standard is 25 quarts per servicing, with a standard cost of 4 per quart. Management has also decided on standard rates for labor and overhead. The standard labor rate is 15 per direct labor hour, the standard variable overhead rate is 8 per direct labor hour, and the standard fixed overhead rate is 12 per direct labor hour. The only remaining decision is the standard for labor usage. To assist in developing this standard, the engineering department has estimated the following relationship between units serviced and average direct labor hours used: As the workers learn more about servicing the new vehicles, they become more efficient, and the average time needed to service one unit declines. Engineering estimates that all of the learning effects will be achieved by the time that 320 units are produced. No further improvement will be realized past this level. Required: 1. Assume that the average labor time is 0.768 hour per unit after the learning effects are achieved. Using this information, prepare a standard cost sheet that details the standard service cost per unit. (Note: Round costs to two decimal places.) 2. CONCEPTUAL CONNECTION Given the per-unit labor standard set, would you expect a favorable or an unfavorable labor efficiency? Explain. Calculate the labor efficiency variance for servicing the first 320 units. 3. CONCEPTUAL CONNECTION Assuming no further improvement in labor time per unit is possible past 320 units, explain why the cumulative average time per unit at 640 units is lower than the time at 320 units. Show that the standard labor time should be 0.768 hour per unit. Explain why this value is a good choice for the per-unit labor standard.arrow_forward
