You are the manager of a monopoly that faces a demand curve described by P = 10 - 20. Your costs are C = 20 + 20. The revenue-maximizing output is Multiple Choice O 1.5. O O 4 OThe first-order condition for a monopoly maximizing its profit is Multiple Choice O P - (dc(Q)/dQ) = 0. O (dR(Q)/dQ) - (dc(Q)/dQ) = 0. O (dR(Q)/dQ) - (dc(Q)/dQ) AC(Q), that is, the average costs decrease as output increases. O MC(Q) = AC(Q)43 Which of the following conditions must hold to ensure that profits are, in fact, at a maximum? Multiple Choice DO:55:15 O d(MC(Q))/dQ > O. O d(MCIQ)/dQ O and d2,joydo?
