B) 40
C) 50
D) 120

Respuesta :

Answer:

C) 50

Explanation:

The additional output produced as a result of employing an additional unit of the variable factor input is called the Marginal Product.

Here we have to calculate the number of additional guests that can be served by the third waiter or marginal product of the third waiter.

Marginal Product of the third waiter = Number of guests served by 3 waiters -  Number of guests served by 2 waiters  

Marginal Product of the third waiter = 120 guests - 70 guests = 50 guests.

Hence, the marginal product of the third waiter is 50 guests.
