Note: round your answers to 2 decimal places. If your answer is negative, leave it as negative. For example, if your answer is -0.125, write -0.13 A monopolist faces market demand curve given by: P = 250 - 0.5Q and a cost function: C(Q) = 100 + 40Q + Q2 (As usual, P represents price and Q represents quantity.) Part a. The price elasticity of demand when Q = 22 units is: and demand is (No answer given) * Part b. The monopolist's profit is maximized when units are produced Part c. The monopolist's average cost is minimized when units are produced Part d. Assume that the government subsidises the monopolist $30 for every unit that it produces and sells. The profit- maximising quantity in this case is
