Marginal product =(change in total product / change in variable input)

Marginal revenue product = Marginal product * Price.

Note: Price = MR becasue price is same at each level of output.

The Marginal revenue product of each level of variable input is lower than the price of factor of production. It implies that, it is not benfeficial for a firm to hire even a single unit of fatcor.

Hence, the profit maximizing quantity of factor is 0 units.

Note: Profit maximizing quantity of factor occurs at the following point.

Marginal revenue product = Price of factor.
