In Figure 7.2, when an additional worker's marginal product diminishes: Figure 7.2 Two graphs stacked vertically-MP in the upper graph, MC in the lower graph; the highest point on MP is at the level of output Q where MC has its lowest point; to the right of the highest point of MP and lowest point of MC is DMR In Figure 7.2, when an additional worker's marginal product diminishes: the cost of producing another unit of output is constant. the cost of producing another unit of output decreases. the cost of producing another unit of output increases. the cost of producing another unit of output can be constant, increase or decrease
