PROBLEMS
1. Sunrise Juice Company sells its output in a perfectly competitive market. The firm's total cost function
is given in the following schedule:
Output
Total Cost
(Units)
($)
0
50
10
120
20
170
30
210
40
260
50

Total costs include a "normal" return on the time (labor services) and capital that the owner has
invested in the firm. The prevailing market price is $7 per unit.
(a)
Prepare (i) marginal cost and (ii) average total cost schedules for the firm.
(b)
What is the firm's profit maximizing output level?
(c)
Is the industry in long-run equilibrium? Justify your answer.
2. Superior Metals Company has seen its sales volume decline over the last few years as the result of
rising foreign imports. In order to increase sales (and hopefully, profits), the firm is considering a price
reduction on luranium--a metal that it produces and sells. The firm currently sells 60,000 pounds of
luranium a year at an average price of $10 per pound. Fixed costs of producing luranium are $250,000.
Current variable costs per pound are $5. The firm has determined that the variable cost per pound
could be reduced by $.50 if production volume could be increased by 10 percent (fixed costs would
remain constant). The firm's marketing department has estimated the arc elasticity of demand for
luranium to be −1.5.
(a)
How much would Superior Metals have to reduce the price of luranium in order to
achieve a 10 percent increase in the quantity sold?
(b)
What would the firm's (i) total revenue, (ii) total cost, and (iii) total profit be before and
after the price cut?
