Exercise G Best Eastern Motel is a regional motel chain. Its rooms rent for $100 per night, on average. The variable cost is$40 a room per night. Fixed costs are $5,000,000 per year. The company currently rents 200,000 units per year, with each unit defined as one room for one night. Should this company undertake an advertising campaign resulting in a$500,000 increase in fixed costs per year, no change in variable cost per unit, and a 10% increase in revenue (resulting from an increase in the number of rooms rented)? What is the margin of safety before and after the campaign?

On the CD player line, the company incurred$2,520,000 of fixed costs per month while selling 20,000 units at $600 each. Variable cost was$240 per unit.

Recently, a new machine used in the production of CD players has become available; it is more efficient than the machine currently being used.

Beyond the numbers—Critical thinking Business decision case A Quality Furniture Company is operating at almost 100% of capacity. The company expects sales to increase by 25% in 2011. To satisfy the demand for its product, the company is considering two alternatives: The first alternative would increase fixed costs by 15% but not affect variable costs. The second alternative would not affect fixed costs but increase variable costs to 60% of the selling price of the company's product. This is Quality Furniture Company's condensed income statement for 2010:  Sales$3,600,000 Costs: Variable $1,620,000 Fixed 330,000 1,950,000 Income before taxes$1,650,000
1. Determine the break-even point in sales dollars for 2011 under each of the alternatives.
2. Determine projected income for 2011 under each of the alternatives.
3. Which alternative would you recommend? Why?

Business decision case B When the Weidkamp Company's plant is completely idle, fixed costs amount to $720,000. When the plant operates at levels of 50% of capacity or less, its fixed costs are$840,000; at levels more than 50% of capacity, its fixed costs are $1,200,000. The company's variable costs at full capacity (100,000 units) amount to$1,800,000.

1. Assuming that the company's product sells for $60 per unit, what is the company's break-even point in sales dollars? 2. Using only the data given, at what level of sales would it be more economical to close the factory than to operate it? In other words, at what level would operating losses approximate the losses incurred if the factory closed down completely? 3. Assume that Weidkamp Company is operating at 50% of its capacity and decides to reduce the selling price from$60 per unit to $36 per unit to increase sales. At what percentage of capacity must the company operate to break even at the reduced sales price? Business decision case C Monroe Company has recently been awarded a contract to sell 25,000 units of its product to the federal government. Monroe manufactures the components of the product rather than purchasing them. When the news of the contract was released to the public, President Mary Monroe, received a call from the president of the McLean Corporation, Carl Cahn. Cahn offered to sell Monroe 25,000 units of a needed component, Part J, for$15.00 each. After receiving the offer, Monroe calls you into her office and asks you to recommend whether to accept or reject Cahn's offer.

You go to the company's records and obtain the following information concerning the production of Part J.

 Costs at current production level (200,000 units) Direct labor $1,248,000 Direct materials 576,000 Manufacturing overhead 600,000 Total cost$2,424,000
You calculate the unit cost of Part J to be $12.12 or ($2,424,000/200,000). But you suspect that this unit cost may not hold true at all production levels. To find out, you consult the production manager. She tells you that to meet the increased production needs, equipment would have to be rented and the production workers would work some overtime. She estimates the machine rental to be $60,000 and the total overtime premiums to be$108,000. She provides you with the following information:

 Costs at current production level (225,000 units) Direct labor $1,404,000 Direct materials 648,000 Manufacturing overhead (including equipmental rental and overtime premiums) 828,000 Total cost$2,880,000
The production manager advises you to reject Cahn's offer, since the unit cost of Part J would be only $12.80 or ($2,880,000/225,000 units) with the additional costs of equipment rental and overtime premiums. This amount still is less than the $15.00 that Cahn would charge. Undecided, you return to your office to consider the matter further. 1. Using the high-low method, compute the variable cost portion of manufacturing overhead. (Remember that the costs of equipment rental and overtime premiums are included in manufacturing overhead. Subtract these amounts before performing the calculation). 2. Compute the total costs to manufacture the additional units of Part J. (Note: include overtime premiums as a part of direct labor.) 3. Compute the unit cost to manufacture the additional units of Part J. 4. Write a report recommending that Monroe accept or reject Cahn's offer. Business decision case D Refer to the "A broader perspective: Major television networks are finding it harder to break even" discussion of cost-volume-profit analysis for television networks. Write a memo to your instructor describing how the networks can reduce their break-even points. Group project E In teams of two or three students, develop a cost-volume-profit equation for a new business that you might start. Examples of such businesses are a portable espresso bar, a pizza stand, a campus movie theater, a package delivery service, a campus-to-airport limousine service, and a T-shirt printing business. Your equation should be in the form: Profits = (Price per unit X Volume) – (Variable cost per unit X Volume) - Fixed costs per period. Pick a period of time, say one month, and project the unit price, volume, unit variable cost, and fixed costs for the period. From this information, you will be able to estimate the profits—or losses—for the period. Select one spokesperson for your team to tell the class about your proposed business and its profits or losses. Good luck, and have fun. Group project F Refer to "A broader perspective: Even colleges use CVP" discussion of how cost-volume-profit analysis is used by colleges. In teams of two or three students, write a memo to your instructor defining step costs and explain why the step costs identified in the case are classified as such. Also include in your memo how the school might lower its break-even point. Group project G In teams of two or three students, address the following questions: • Why would a company consider increasing automation and decreasing the use of labor if the result would be an increase in the break-even point? • Would an increase in automation increase fixed costs over the short-run, long-run, or both? Write a memo to your instructor that addresses both questions. Be sure to explain your answers.
