1 SECTION A: Multiple Choice Questions: (50 Marks) ANSWER ALL QUESTIONS: 1. You are the manager of a monopoly that faces a demand curve described by P = 230 20Q. Your costs are C = 5 + 30Q. Your firm's maximum profits are A. 495. B. 475. C. 480. D. 415. 2. You are the manager of a firm that produces output in two plants. The demand for your firm's product is P = 120 6Q, where Q = Q 1 + Q 2 . The marginal cost associated with producing in the two plants are MC 1 = 2Q 1 and MC 2 = 4Q 2 . How much output should be produced in plant 1 in order to maximize profits? 3. You are a manager in a perfectly competitive market. The price is \$14. Your total cost curve is C(Q) = 10 + 4Q + 0.5 Q 2 . What level of output should you produce in the short run? 4.
