Answer:
The marginal revenue product of the last worker he hired is $8 per hour and the worker's marginal product is 5 boxes
Explanation:
The computation of the marginal revenue product of the last worker is shown below:
The marginal revenue product of the last worker would be $8 as the same wage rate is applied to all the workers.
And, the worker's marginal product would be equal to
= Wage rate per hour ÷ selling price per box
= $8 ÷ $1.60
= 5 boxes
