Sami owns a cookie shop. Sami can bake 100 dozen cookies per day. She is considering hiring her husband Nevin to work for her. Together Sami and Nevin can bake 175 dozen cookies per day. What is Nevin's marginal product

Explanation:

The marginal product is defined as the change in the output resulting from employing one more unit of a input.

If your input is number of days and the output is number of cookies, then the marginal product is the number of additional cookies that can be produced by working one additional day.

By the context, the baking rates, number of cookies baked per day, for both Nevin and Sami are constant.

To calculate the individual baking rates, just set an equation:

Calling r Nevin's rate:

Thus, Nevin produces 75 dozen cookies per additional day worked and that is his marginal product.
