1. Pete’s Choppers Company’s cost data have been partially entered in the table. Following
the arrest of the company’s accountant, you are called to fill in the missing entries:

2. Kobe’s production function for mini-basketball hoops is Q = LK. The price of labor
services is w and the price of capital services is r. Suppose that w = $4, r = $2, and
Kobe’s total cost is $160.
(a) What is Kobe’s MPL and MPK?
(b) What is Kobe’s optimal input combination of L and K? What is Q?
(c) Suppose the wage rate is 8 times the rental rate and Q is the same as before. What is
Kobe’s optimal input combination of L and K after the price change?

3. Suppose that each firm in a perfectly competitive industry has the short-run cost function
C 5 q 2q2, and the market price is $45. What is the profit-maximizing output level
for each firm? What is the total revenue? What are the profits?
4. Suppose that a perfectly competitive firm’s total cost of producing output q is TC (q) =
10+10q-q2+0.25q3 and market price P*=$10.
(a) Find the short-run supply curve of a firm in this industry.
(b) How much will the firm produce at P*=$10?

5. Crystal skulls are produced in a perfectly competitive industry in which each firm has a
total cost function TC = 4r + wq2/4, where r is the price of a barrel of oil and w is the
price of a barrel of water. Suppose that the crystal skull industry is in long-run
equilibrium, with r = $25 and w = $1. What is the market price of a crystal skull? How
many skulls does each firm produce?
