Question

Use the following to answer questions 3-8: ​ Number of Workers Total Cost 0 1000 1 2200 2 3200 3 4000 4 4600 5 5000 6 5200 7 5600 8 6200 9 7000 10 8000 If hiring the 4th worker increases total product by 50 units and the price of each unit is $15,​ a. ​the firm should not hire the 4th worker as MRMC c. ​marginal revenue equals $150 d. ​the firm should not hire the 4th worker as MR

Answer 1

Firm should hire the 4th worker as MR > MC.

Step-by-step explanation:

Here, we are comparing the marginal cost of hiring 4th worker with the revenue generated by the 4th worker.

Marginal cost of hiring 4th worker:

= Total cost with 4 workers - Total cost with 3 workers

= $4,600 - $4,000

= $600

Total revenue generated by the 4th worker:

= Number of units produced by 4th worker × Price of each unit

= 50 × $15

= $750

Therefore, the firm should hire the 4th worker as the marginal revenue of 4th worker is greater than its marginal cost.
