a. Complete the table.
b. Graph AVC, ATC, and MC on the same graph. What is the relationship between the MC curve and the ATC, and between MC and AVC?
c. Suppose that market price is $30. How much will the firm produce in the short run? How much are total profits?
d. Suppose that market price is $50. How much will the firm produce in the short run? What are total profits?
e. Suppose that market price is $10. How much would the firm produce in the short run? What are total profits?
2. The following problem traces the relationship between firm decisions, market supply, and market equilibrium in a perfectly competitive market.

b. Using the information in the table, fill in the following supply schedule for this individual firm under perfect competition, and indicate profit (positive or negative) at each output level. (Hint: At each hypothetical price, what is the MR of producing one more unit of output? Combine this with the MC of another unit to figure out the quantity supplied.)
