(a) Graph demand for a market where P(y) = 100 - -y. Label this demand curve D. (2 points) (b) Calculate the Marginal Revenue function for a monopolist in this market. Graph this Marginal Revenue function in the same graph, labeling it MR. (2 points) (c) Calculate and graph the Marginal Cost curve in the same graph (labeling it MC, when the monopolist's total cost function is C(y) = 40y + 90 (2 points) (d) Identify the monopolist's profit-maximizing quantity and price, and mark that price-quantity point with a star on the demand curve in your graph.
