Chapter 3, Problem 21E
Sweet Dreams Bakery was started five years ago by Della Fontera who was known for her breads, sweet rolls, and personalized cakes. Della had kept her accounting system simple, believing that she had a good intuitive handle on costs. She had been using the following formula to describe her monthly overhead costs:
Overhead cost = $7,800 + $7.50 (direct labor hours)
For breads and sweet rolls that were available in the bakery case each day, she applied a standard pricing system. For special orders, however, Della needed her cost formula to help her come up with an estimated cost for the personalized cake or wedding cake. To that cost, she applied a markup percentage.
Lately, however, the increase in the variety of orders and the elaborateness of the wedding cakes made her wonder if a more sophisticated view of costs would help her in planning, budgeting, and pricing.
After some late-night discussions with her workers, Della determined that Sweet Dreams’ expansion into wedding cakes and gift baskets had made special orders a more complex operation. The various shapes of the wedding cake tiers had required Della’s investing in different- sized cake pans, as well as decorating tips for icing. The different icing patterns and elaborate designs took much more time for icing, as well. In addition, while a five-year-old’s birthday cake just requires that the child’s name and (possibly) the superhero’s name are spelled correctly, a wedding cake is a once-in-a-lifetime item that must achieve perfection. (Della hated to use the term “bridezilla” but.…) Gift baskets required Della to stock baskets, cellophane, and bows. Then when an order came in, a worker had to stop baking to arrange the muffins and breads artfully in the basket, wrap it, and tie the bow. While it seemed simple enough, this took time and thought. Thus, the number of direct labor hours was still an important variable, but so were the number of wedding cakes and gift baskets. Della rummaged through her college textbooks and found information on regression. Then, with help from one of her computer savvy workers, she ran multiple regression tables for the past 24 months of data for Sweet Dreams for three independent variables: number of direct labor hours, the number of wedding cakes, and the number of gift baskets. The following printout was obtained:
Required:
- 1. Write out the cost equation for Sweet Dreams’ monthly overhead cost.
- 2. Suppose that next month Sweet Dreams expects to have 550 direct labor hours, 35 wedding cakes, and 20 gift baskets. What is the expected overhead? (Round to the nearest dollar.)
- 3. What does R2 mean in this equation? Overall, what is your evaluation of the cost equation that was developed for the cost of overhead? Suppose that Sweet Dreams charges an extra $2.50 to prepare a gift basket. This charge is in addition to the price charged for the items (e.g., muffins) that the customer chooses to put into the basket. How might Della use the results of the regression equation to see whether or not the $2.50 charge is appropriate?

Nizam Sanjay, a member of the controllers department, believes that overhead activities and costs should be classified into groups that have the same driver. He has decided that unloading incoming goods, counting goods, and inspecting goods can be grouped together as a more general receiving activity, since these three activities are all driven by the number of receiving orders. The 10 months of data shown below have been gathered for the receiving activity. Required: 1. Prepare a scattergraph, plotting the receiving costs against the number of purchase orders. Use the vertical axis for costs and the horizontal axis for orders. 2. Select two points that make the best fit, and compute a cost formula for receiving costs. 3. Using the high-low method, prepare a cost formula for the receiving activity. 4. Using the method of least squares, prepare a cost formula for the receiving activity.

- You are a management accountant for Time Treasures Company, whose company has recently signed an outsourcing agreement with Spotless. Inc., a janitorial service company. Spotless will provide all of Time Treasures janitorial services, including sweeping floors, hauling trash, washing windows, stocking restrooms, and performing minor repairs. Time Treasures will be billed at an hourly rate based on the type of service performed. The work of common laborers (sweeping, hauling trash) is to be billed at $8 per hour. More skilled (repairs) and more dangerous work (washing outside windows on the 23rd floor) are to be billed at $18 per hour. Supervisory time is to be billed at $20 per hour. Spotless will submit monthly invoices, which will show the number and types of hours for which Time Treasures is being charged. The outsourcing contract is simple and straightforward. A. What are some of the internal control problems you foresee as a result of our sourcing the janitorial service with this contract? B. Explain recommendations to control risk that would you suggest after reviewing the contract.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_forwardBrees, Inc., a manufacturer of golf carts, has just received an offer from a supplier to provide 2,600 units of a component used in its main product. The component is a track assembly that is currently produced internally. The supplier has offered to sell the track assembly for 66 per unit. Brees is currently using a traditional, unit-based costing system that assigns overhead to jobs on the basis of direct labor hours. The estimated traditional full cost of producing the track assembly is as follows: Prior to making a decision, the companys CEO commissioned a special study to see whether there would be any decrease in the fixed overhead costs. The results of the study revealed the following: 3 setups1,160 each (The setups would be avoided, and total spending could be reduced by 1,160 per setup.) One half-time inspector is needed. The company already uses part-time inspectors hired through a temporary employment agency. The yearly cost of the part-time inspectors for the track assembly operation is 12,300 and could be totally avoided if the part were purchased. Engineering work: 470 hours, 45/hour. (Although the work decreases by 470 hours, the engineer assigned to the track assembly line also spends time on other products, and there would be no reduction in his salary.) 75 fewer material moves at 30 per move. Required: 1. Ignore the special study, and determine whether the track assembly should be produced internally or purchased from the supplier. 2. Now, using the special study data, repeat the analysis. 3. Discuss the qualitative factors that would affect the decision, including strategic implications. 4. After reviewing the special study, the controller made the following remark: This study ignores the additional activity demands that purchasing would cause. For example, although the demand for inspecting the part on the production floor decreases, we may need to inspect the incoming parts in the receiving area. Will we actually save any inspection costs? Is the controller right?arrow_forward
