Answer:
3 workers
Explanation:
At optimal point, wage = Price * Marginal Product of Labour (MPL)
When 3 workers are employed,
Since wage is given = 25
And price = 4
When 3 workers are hired, wage is close to price * MPL because wage = 25 and p*MPL = 24
OR
salary paid = $25*3 = $75
Revenue generated = 24*$4= $96
This combination provides the best profit margin which is 96 - 75 = $21.
