A graph of price, P, versus quantity, Q, shows a supply curve, S, rising linearly from (0, 30) to (28, 86), and a demand curve, D, descending linearly from (0, 150) to (28, 38). The curves intersect at (20, 70). A point on Curve D at (10, 110), is shown. Refer to Figure 7-2. At the equilibrium price, consumer surplus is $1,600. $800. $1,400. $700
