Assume that the units of variable input in a coal-production process are 1, 2, 3, 4, and 5 and the corresponding total outputs (in tons) are 10, 19, 26, and 31, respectively.The marginal product of the third unit of input must be 7 tons.

Question

Quizplus · Accepted Answer

The marginal product of the third unit of input is calculated as the change in total output when the third unit of input is added. From the data, adding the third unit of input increases total output from 19 tons to 26 tons, which is an increase of 7 tons.
