a) Using the schedule provided, calculate the marginal product of labor when K = 3.

b) Using your calculations, for which workers are there increasing, decreasing, and negative marginal returns to labor?

c) Suppose this bakery decides to add another unit of capital in the long-run.Find the marginal product of the 4th unit of capital and the marginal product of labor when K = 4.
