Joe owns a coffee house and produces coffee drinks under the production function q = 5KL where q is the number of cups generated per hour, K is the number of coffee machines (capital), and L is the number of employees hired per hour (labor). What is the marginal product of labor?

Marginal Product of Labour = 5K

Step-by-step explanation:

Marginal product of labor is the change in output when additional labor is added,

To calculate marginal product of labor you simply divide the change in total product by the change in labour.

Marginal product of labour (MPL) = Change in total products / Change in labour

Here, change in labour = 5KL

Change in labour = L

MPL = 5KL/L

MPL = 5K
