A graph plots Price (dollar per unit) versus Quantity (units per week). In the graph, the horizontal axis ranges from 0 to 80 with an increment of 20 units. The vertical axis ranges from 0 to 100 with an increment of 20 units. The graph plots two slopes from top left to mid-right and bottom left respectively, a horizontal line from (0, 50) to (80, 50) is labeled M C, and three closed points (20, 50), (20, 75), and (40, 50). The first slope that falls through (0, 100) to (40, 0) is labeled M R and the second slope that falls through (0, 100) to (80, 0) is labeled D.
