A purely competitive wheat farmer can sell any wheat he grows for $20 per bushel. His five acres of land show diminishing returns, because some are better suited for wheat production than others. The first acre can produce 1000 bushels of wheat, the second acre 900, the third 800, and so on. Fill in the table given below to answer the following questions. How many bushels will each of the farmer’s five acres produce? How much revenue will each acre generate? What are the TR and MR for each acre?
