A firm produces three products in a repetitive process facility. Product A sells for $60;
its variable costs are $20. Product B sells for $200; its variable costs are $80. Product C
sells for $25; its variable costs are $15. The firm has annual fixed costs of $320,000.
Last year, the firm sold 1000 units of A, 2000 units of B, and 10,000 units of C.
Calculate the break-even point of the firm. The firm has some idle capacity at these
volumes, and chooses to cut the selling price of A from $60 to $45, believing that its
sales volume will rise from 1000 units to 2500 units. What is the revised break-even
point?
A firm is weighing three capacity alternatives: small, medium, and large job shop.
Whatever capacity choice is made, the market for the firm's product can be "moderate"
or 'strong." The probability of moderate acceptance is estimated to be 40 percent; strong
acceptance has a probability of 60 percent. The payoffs are as follows. Small job shop,
moderate market = $24,000; Small job shop, strong market = $54,000. Medium job
shop, moderate market = $20,000; medium job shop, strong market = $64,000. Large
job shop, moderate market = -$2,000; large job shop, strong market = $96,000. Which
capacity choice should the firm make?
