Answer: Marginal revenue product of the second worker is $24.
Explanation: Marginal revenue product is the addition to total revenue when one unit of a good is produced and sold in the market. It is given by,
[tex] MRP = MR * MP_{L} [/tex]
Marginal Product of the second worker is
[tex] MR_{2} = TR_{2} - TR_{1} = 32 - 24= 8 [/tex]
Marginal revenue is the addition to total revenue when one more unit of a good is produced. Since, the price is $3 the marginal revenue of an additional output is $3.
[tex] MRP_{2} = 3 * 8 = $24 [/tex]
Marginal Revenue Product of the second worker is $24.
