Industry Supply. Columbia Pharmaceuticals, Inc., and Princeton Medical, Ltd., supply a generic drug equivalent of an antibiotic used to treat postoperative infections. Proprietary cost and output information for each company reveal the following relations between marginal cost and output:

The wholesale market for generic drugs is vigorously price-competitive, and neither firm is able to charge a premium for its products. Thus, P = MR in this market.
A. Determine the supply curve for each firm. Express price as a function of quantity and quantity as a function of price. (Hint: Set P = MR = MC to find each firm's supply curve.)
B. Calculate the quantity supplied by each firm at prices of $5, $7.50, and $10. What is the minimum price necessary for each individual firm to supply output?
C. Determine the industry supply curve when P < $6.
D. Determine the industry supply curve when P > $6. To check your answer, calculate quantity at an industry price of $10 and compare your answer with part B.
