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?
