When the price of a good falls and the prices of other goods and a consumer's income remain the same, explain what happens to the consumption of the good whose price has fallen and to the consumption of other goods
What will be an ideal response?
When the price of a good falls, the marginal utility per dollar for that good increases. The marginal utility per dollar for other goods does not change. To maximize total utility, a consumer makes marginal utility per dollar equal for all goods, so the consumer buys more of the good that has experienced the fall in price and less of the goods whose marginal utilities per dollar have not changed.

A monopolist faces a demand curve Q = 120 - 2p and has costs given by C(Q) = 20Q + 100
a. Write the monopolist's profits in terms of the price it charges. b. Use the derivative (w.r.t. price) to determine the monopolist's profit-maximizing price. c. Now, derive the monopolist's inverse demand based on the demand equation above. Write out the monopolist's profits in terms of quantity. d. Use the derivative w.r.t. Q to determine the monopolist's optimal quantity. What price does the monopoly charge?
