8. Problems and Applications Q8
Henry Potter owns the only well in town that produces clean drinking water. He faces the following demand, marginal revenue, and marginal cost
curves:
Demand:
P = 70-Q
Marginal Revenue: MR = 70-20
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
symbol) to indicate the profit-maximizing price and quantity.
