The market demand function: Pb 240-4Qd TR = 240Q-402 MR 240-8Q TC = Q^2 + 400 + 150MC = 2Q +40 MR = MC 240-80-2Q 40 Q=20 By substituting the value of Q in the price equation, P 240-4Q P 240-4*20 P= 160 TC = 4By substituting the value of Q in the price equation, P-240-4Q P = 240-4*25 P 140 C. TC= 150 MC 0 MR MC 240-80 = 0 Q-30 By suMonopolist quantity Monopolist price 20 25 30 160 1A0 120
