Question

Harry owns a snow-removal business. He hires workers to shovel driveways for him during the winter. The first worker he hires can shovel twelve driveways in one day. When Harry hires two workers, they can shovel a total of 22 driveways in one day. When Harry hires a third worker, he shovels an additional eight driveways in one day. Suppose that Harry pays each worker $80 per day and that he charges each customer $20 to have his driveway shoveled. What is the value of the marginal product of labor for the second worker

Answer 1

The answer is "200".

Step-by-step explanation:

Let:

`Labour \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Total Labour Product }\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{The marginal Labour Product}\\\\`

`12\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ (12*20)=240 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -\\\\22\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ (22*20)=440 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 440-240 = 200\\\\30 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ (30*20)=600 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 600-440 = 160\\\\`

In the above-given table 12,22, and 30 values are multiplied by 20 since each client is paid $20 per driveway change, that's why it indicates that the second worker's marginal product is the (200).
