He faces the following demand, marginal revenue, and marginal cost urves: Demand: P = 70 - Q Marginal Revenue: MR = 70 - 2Q Marginal Cost: MC = 10 + Q On the following graph, use the blue line (circle symbol) to graph Mr. Potter's demand curve. Then, use the black line (cross symbol) to graph his marginal revenue (MR) curve. Next, use the orange line (square symbol) to graph his marginal cost (MC) curve. Finally, use the grey point (star F symbol) to indicate the profit-maximizing price and quantity. O Demand + MR Price (Dollars) MC
