The first, second, and third workers employed by a firm add 24, 18, and 9 units to total product respectively. Therefore, the: Group of answer choices marginal product of the third worker is 9. total product of the three workers is 54. average product of the three workers is 18. marginal product of the first worker is 18.

marginal product of the third worker is 9.

Explanation:

Marginal product is the change in total product of labour as a result of increase labour by one unit

Marginal product = change in total product / change in labour

marginal product of third worker = (18 - 9) / (3 - 2) = 9

Total product is the sum of each individual total product = 24 + 18 + 9 = 51

Average product = total product /3 = 51 / 3 = 17

i would say a penny hope it you
