To find the marginal product of the 2nd worker, we need to calculate how many additional cookies are produced by adding the 2nd worker to the team.

The production with one worker is 15 cookies, so we know that the first worker produces 15 cookies.

The production with two workers is 35 cookies, which means that the second worker contributes (35-15)=20 additional cookies. Therefore, the marginal product of the 2nd worker is 20 cookies.

So the best choice is B, with an explanation as above.

Suppose That One Worker Can Produce 15 Cookies, Two Workers
