Answer:
Option (b) is correct.
Step-by-step explanation:
Given that,
With 15 workers, output produced per day = 325 units
With 16 workers, output produced per day = 340 units
Marginal product of labor refers to the additional output produce by the employment of an additional labor into the production of a good. It is also defined as the change in the level of output by employing an additional unit of labor.
Therefore, the the marginal product of the 16th worker is the difference between the output produced by the 16 workers and output produced by the 15 workers. It is calculated as follows:
= Output produced per day by 16 workers - Output produced per day by 15 workers
= 340 units - 325 units
= 15 units of output.
