2. Suppose a pure monopolist faces the following demand schedule and the same cost data as the competitive producer discussed in
problem 4 at the end of Chapter 10. Calculate the missing TR and MR amounts, and determine the profit-maximizing price and
profit-maximizing output for this monopolist. What is the monopolist's profit? Verify your answer graphically and by comparing total
revenue and total cost. LO11.4
