Figure 4-18 A graph of price versus quantity shows a demand curve, D, a straight line descending from (0, 45), to (600, 15), and a supply curve, S, a straight line ascending from (0, 5) to (600, 35). The curves intersect at (400, 25). On Curve D the points (200, 35), (300, 30), (400, 25), (500, 20), and (600, 15) are shown. On Curve S, the points (200, 15), (300, 20), (400, 25), (500, 30), and (600, 35), are shown. Refer to Figure 4-18. At what price would there be an excess supply of 200 units of the good? Group of answer choices $30 $20 $35 $15
