A firm hires labor in a perfectly competitive labor market. Its current profit-maximizing hourly output is 100 units, which the firm sells at a price of $5 per unit. The Marginal Physical product (MPP) of the last unit of labor employed is 5 units per hour. The firm pays each worker an hourly wage of $15. a)What Marginal Revenue (MR) does the firm earn from sale of the output produced by the last worker employed? b)Does this firm sell its output in a perfectly competitive market?

A.Marginal Revenue $3

B. No

Explanation:

A.Calculation for the Marginal Revenue (MR) that the firm earn from sale of the output produced by the last worker employed

Based on the information given we were told that the Marginal Physical product of the last unit of labor was 5 units per hour in which the firm pays each worker an hourly wage of $15. Now let calculate the Marginal Revenue using this formula

Marginal Revenue = Employees hourly wages/Marginal Physical product unit of labor

Where,

Employees hourly wages=$15

Marginal Physical product unit of labor =5 units per hour

Let plug in the formula

Marginal Revenue =$15/5

Marginal Revenue =$3

B. No reason been that the current profit-maximizing hourly output was 100 units in which we were told that the firm sells at a price of $5 per unit. While the Marginal Revenue gotten in (A) above was $3 which is lesser or lower than $5 per unit which simply means that the firm does NOT sell its output in a well perfectly competitive market .
