Question

A carpenter hammers nails each day at work. During the first hour she can hammer 120 nails, the second hour 100 nails, the third hour 90 nails, the fourth hour 60 nails, and the fifth hour 10 nails. Her marginal product in the third hour is _____ nails.

Answer 1

90

Step-by-step explanation:

Marginal product is the change in total output when an additional unit of input is added. In this example the unit of input is every 1 hour spend on work and output is amount of output for the additional hour. Third hour is the one additional hour used in which 90 nails have been hammered. So, marginal product for third hours is 90 nail.
