A farm can produce 10,000 bushels of wheat per year with 5 workers and 13,000 bushels with 6 workers. The marginal product of the sixth worker for this farm is:
10,000 bushels.
3,000 bushels.
500 bushels.
23,000 bushels.
The marginal product of the sixth worker is the additional output produced by adding the sixth worker.
So, the marginal product of the sixth worker would be:
13,000 bushels - 10,000 bushels = 3,000 bushels
Therefore, the correct answer is 3,000 bushels.
