4. A monopolist faces a demand curve given by p(q) = 36 -q and has a cost curve equal to C(q) = 30q - -q2. Calculate the profit-maximizing price and quantity: Hint: note that C(q) = 30q - 2q' is the total cost function, not the marginal cost. (a) p = 28 (b) p = 24 9 = 12 (c) p = 30 9=6 (d) p = 33.6 q = 2.4 (e) p = 32 9=4
