Choose labor input in a competitive factor market by comparing marginal revenue product with the market wage and calculating hiring outcomes.
The table provided shows the short-run production function for Lowen Feline, a profit-maximizing firm that produces cat food.

Lowen Feline sells as many bags of cat food as it wants at a market price of $ 10 per bag and hires as many workers as it wants at a market wage of $ 18.
Determine the profit-maximizing number of workers Lowen Feline will hire. Explain using marginal analysis.
State that the profit-maximizing number of workers is 7 and explain that the marginal
revenue product (MRP) of the 7th worker ($ 20) is greater than the marginal factor cost
(MFC) of the 7th worker (wage =$ 18 ), and that the hiring of the 8th worker would
decrease profits because the MRP of the 8th worker ($10) is less than the MFC of the 8th
worker (wage = $18).
