Afirm currently employs four workers in a sandwich shop, and produces sandwiches at a total cost per sandwich (atc) of $3. the sandwiches sell for $5. if the marginal cost of hiring another worker to produce sandwiches is $5.50 per sandwich, then:

a. it will cost $5.50 to make another sandwich, which can only be sold for $5.
b. the firm will lose $0.50 per sandwich if it hires another worker.
c. the firm should not hire a fifth worker.

all are correct A, B and C

Explanation:

The marginal cost hiring another worker and producing a sandwich = $5.50 per sandwich, which is higher than the marginal revenue.

If the selling price per sandwich is $5 and the marginal cost per sandwich is $5.50, the firm will lose $0.50 for every sandwich that it sells.

Therefore the firm would be losing money is they hire an extra worker.

In order to maximize the profit, the marginal cost = selling price.
