Graphic Printing Company currently leases its only copy machine for $2,000 a month. The company is considering replacing this leasing agreement with a new contract that entirely commission based. Under the new agreement, Graphic would pay a commission for its printing at a rate of $20 for every 500 pages printed. The company currently charges $0.32 per page to its customers. The paper used in printing costs the company S0.02 per page and other variable costs, including hourly labor, amount to $0.10 per page. Read the requirements 1. What is the company's breakeven point under the current leasing agreement? What is it under the new commission-based agreement? 2. For what range of sales levels will Graphic prefer (a) the fixed lease agreement and (b) the commission agreement? 3. Graphic estimates that the company is equally likely to sell 18,000, 28,000, 38,000, 48,000, or 58,000 pages of print. Using information from the original problem, prepare a table that shows the expected profit at each sales level under the fixed leasing agreement and under the commission-based agreement. What is the expected value of each agreement? Which agreement should Graphic choose? Requirement 1. What is the company's breakeven point under the current leasing agreement? What is it under the new commission-based agreement? First, determine the formula used to calculate the breakeven point in units, then calculate the company's breakeven point under the current leasing agreement (Enter a "0" for any zero balances.) Fixed costs Contribution margin per unit Breakeven number of units $ 2,000 0.20 10,000 What is it under the new commission-based agreement? (Enter a "0" for any zero balances.) The company's breakeven point under the new commission-based agreement is 0 units. Requirement 2. For what range of sales levels will Graphic prefer (a) the fixed lease agreement and (b) the commission agreement? In order to determine the range of sales levels Graphic would prefer for each agreement, we must first calculate the indifference point. The indifference point = sales volume at which the income from alternative 1 equals the income from alternative 2 Now calculate the indifference point. (Round to the nearest whole number.) The indifference point is at 50,000 units Graphic would prefer the fixed lease agreement at sales more than the indifference point The commission based agreement would be preferred at 0 units up to the indifference point Requirement 3. Graphic estimates that the company is equally likely to sell 18,000, 28,000, 38,000, 48,000, or 58,000 pages of print. Using information from the original problem, prepare a table that shows the expected profit at each sales level under the fixed leasing agreement and under the commission-based agreement. What is the expected value of each agreement? Which agreement should Graphic choose? Begin with the fixed leasing agreement. (Use parentheses or a minus sign for losses.) Fixed leasing agreement Expected Sales level Profit/(Loss) Profit/(Loss) 18,000 $ 1,600 $ 320 $ 3,600 $ 720 38,000 $ 5,600 $ 1,120 48,000 $ 7,600 $ 1,520 58,000 $ 9,600 $ 1,920 $ 5,600 Total expected profit/(loss) 28,000 Next, calculate the expected profit at each sales level under the commission based agreement. Commission-based agreement Expected Sales level Profit/(Loss) Profit/(Loss) 18,000 28,000 38,000 48,000 58,000 Total expected profit/(loss)
