Answer: The answer is given below
Explanation:
The marginal revenue product of labor (MRPL) is an additional amount of revenue that a firm will make when it hires one additional employee. The formula and r calculating
MRPL = marginal product of labour x marginal revenue.
It should be noted that P = MC = MR. Therefore marginal revenue will be $20.
Therefore when:
MPPL = 0
MRPL = 0 × 20 = 0
MPPL = 20
MRPL = 20 ×20 = 400
MPPL = 19
MRPL = 19 × 20 = 380
MPPL = 18
MRPL = 18 × 20 = 360
MPPL = 15
MRPL = 15 × 20 = 300
MPPL = 12
MRPL = 12 × 20 = 240
Check the attached file for the table.

The completion of the column for the marginal revenue product of labor (MRP) is as follows:
Labor (Number of Output Marginal Product of Value of the
workers) (Units of output) Labor (Units of output) Marginal Product
of Labor (Dollars)
1 20 20 $400 (20 x $20)
2 39 19 $380 (19 x $20)
3 57 18 $360 (18 x $20)
4 72 15 $300 (15 x $20)
5 84 12 $240 (12 x $20)
The marginal revenue product of labor (MRPL) shows the additional amount of revenue the firm generates when it adds one additional employee to its labor force. It is the product from the multiplication of the marginal product of labor by the selling price of output.
Thus, according to the law of Marginal Revenue Product of Labor, the company will demand more labor until its MRPL equals the wage rate, that is at $360.
