Figure 6-3 A graph of price, P, versus quantity, Q, shows a supply curve, S, and a demand curve, D. Curve S is a straight line rising from the origin with a slope of 1. Curve D is a straight line descending from (0, 40) with a slope of 1. The curves intersect at point (20, 20). Refer to Figure 6-3. A government-imposed price of $24 in this market is an example of a a. binding price ceiling that creates a shortage. b. nonbinding price floor that creates a surplus. c. binding price floor that creates a surplus. d. nonbinding price ceiling that creates a shortage
