Madison Electric Company uses a fossil fuel (coal) plant for generating electricity. the facility can generate 900 megawatts (million watts) per hour. The plant operates 600 hours during March. Electricity is used as it is generated; thus, there are no inventories at the beginning or end of the period. The March conversion and fuel costs are as follows:
Conversion costs | $40,500,000 |
Fuel | 10,800,000 |
Total | $51,300,000 |
Madison also has a wind farm that can generate 100 megawatts per hour. the wind farm receives sufficient wind to run 300 hours for March. The March conversion costs for the wind farm (mostly
Conversion costs | $2,700,000 |
a. Determine the cost per megawatt hour (MWh) for the fossil fuel plant and the wind farm to identify the lowest cost facility in March,
b. Why are equivalent units of production not needed in determining the cost per megawatt hour (MWh) for generating electricity?
c. What advantage does the fossil fuel plant have over the wind farm?

Calculate the product cost for one tent. Calculate the total product cost for last year. 2. CONCEPTUAL CONNECTION Prepare an income statement for external users. Did you need to prepare a supporting statement of cost of goods manufactured? Explain. 3. CONCEPTUAL CONNECTION Suppose 200,000 tents were produced (and 200,000 sold) but that the company had a beginning finished goods inventory of 10,000 tents produced in the prior year at 40 per unit. The company follows a first-in, first-out policy for its inventory (meaning that the units produced first are sold first for purposes of cost flow). What effect does this have on the income statement? Show the new statement.arrow_forwardZippy Inc. manufactures a fuel additive, Surge, which has a stable selling price of 44 per drum.

Empty drums: 94,000 purchased at a cost of 94,000; 80,000 drums used. Direct labor: 81,000 hours worked at a cost of 816,480. Factory overhead: 768,000. Required: Calculate the following for September, using the formulas on pages 421422 and 424 (Round unit costs to the nearest whole cent and compute the materials variances for both Surge and for the drums.): 1. Materials quantity variance. 2. Materials purchase price variance. 3. Labor efficiency variance. 4. Labor rate variance.arrow_forward
- Standard unit cost and journal entries The normal capacity of Algonquin Adhesives Inc. is 40,000 direct labor hours and 20,000 units per month. A finished unit requires 6 lb of materials at an estimated cost of 2 per pound. The estimated cost of labor is 10.00 per hour. The plant estimates that overhead (all variable) for a month will be 40,000. During the month of March, the plant totaled 34,800 direct labor hours at an average rate of 9.50 an hour. The plant produced 18,000 units, using 105,000 lb of materials at a cost of 2.04 per pound. 1. Prepare a standard cost summary showing the standard unit cost. 2. Make journal entries to charge materials and labor to Work in Process.arrow_forwardPlata Company has identified the following overhead activities, costs, and activity drivers for the coming year: Plata produces two models of microwave ovens with the following activity demands: The companys normal activity is 21,000 machine hours.

- The activity of moving materials uses four forklifts, each leased for 18,000 per year. A forklift is capable of making 5,000 moves per year, where a move is defined as a round trip from the plant to the warehouse and back. During the year, a total of 18,000 moves were made.

On June 1 of the current year, 6,400 units were completed in the Blending Department. During June, 55,000 units entered the Blending Department from the Refining Department. During June, the units in process at the beginning of the month were completed. Of the 55,000 units entering the department, all were completed except 5,200 units that were completed. The equivalent units for conversion costs for June for the Blending Department were computed as follows: List the errors in the computation of equivalent units for conversion costs for the Blending Department for June.arrow_forwardDuring the week of June 12, Harrison Manufacturing produced and shipped 15,000 units of its aluminum wheels: 3,000 units of Model A and 12,000 units of Model B.

- Step Costs, Relevant Range Bellati Inc. produces large industrial machinery. Bellati has a machining department and a group of direct laborers called machinists. Each machinist can machine up to 500 units per year. Bellati also hires supervisors to develop machine specification plans and oversee production within the machining department. Given the planning and supervisory work, a supervisor can oversee, at most, three machinists. Bellatis accounting and production history shows the following relationships between number of units produced and the annual costs of supervision and materials handling (by machinists): Required: 1. Prepare a graph that illustrates the relationship between direct labor cost and number of units produced in the machining department. (Let cost of direct labor be the vertical axis and number of units be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost? 2. Prepare a graph that illustrates the relationship between the cost of supervision and the number of units produced. (Let cost of supervision be the vertical axis and number of units be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost? 3. Suppose that the normal range of production is between 1,400 and 1,500 units and that the exact number of machinists is currently hired to support this level of activity. Further suppose that production for the next year is expected to increase by an additional 500 units. What is the increase in the cost of direct labor? Cost of supervision?arrow_forwardDuring the week of May 10, Hyrum Manufacturing produced and shipped 16,000 units of its aluminum wheels: 4,000 units of Model A and 12,000 units of Model B.
