Let L represent the number of workers hired by a firm,and let Q represent that firm's quantity of output.Assume two points on the firm's production function are (L = 12,Q = 122)and (L = 13,Q = 132).Then the marginal product of the 13th worker is
A) 8 units of output.
B) 10 units of output.
C) 122 units of output.
D) 132 units of output.

The marginal product of labor (MPL) is the additional output that results from hiring one more worker while holding other inputs constant. It can be calculated as:

MPL = (change in output) / (change in labor)

Using the two given points:

MPL = (132 - 122) / (13 - 12) = 10

Therefore, the marginal product of the 13th worker is 10 units of output.
