Problem 08-10
The manager of a local monopoly estimates that the elasticity of demand for its product is constant and equal to –3. The firm’s marginal cost is constant at \$20 per unit.a. Express the firm’s marginal revenue as a function of its price.

b. Determine the profit-maximizing price
Problem 08-14 (Algo)
You are the manager of a small pharmaceutical company that received a patent on a new drug three years ago. Despite strong sales (\$125 million last year) and a low marginal cost of producing the product (\$0.40 per pill), your company has yet to show a profit from selling the drug. This is, in part, due to the fact that the company spent \$2 billion developing the drug and obtaining FDA approval. An economist has estimated that, at the current price of \$1.20 per pill, the own price elasticity of demand for the drug is -1.5.Based on this information, what can you do to boost profits?
