Question

Hester operates a hand car wash service and charges customers $10 per car wash. Based on her knowledge of operations, the 100th car in a day costs her $9.95 to wash. If she takes additional business, however, the 101st car will cost her $10.05 to wash. Does she take the additional business? Group of answer choices No, because she has hidden costs that far exceed her estimate of $10.05, so she loses money. No. She turns away business when the cost of an additional unit exceeds the income from it. No, because taking on additional business doesn’t earn her any money. Yes, because if she turns away business, his service will be forced to close. Yes. More business means more revenue, and more revenue means more profits.

Answer 1

Answer: No. She turns away business when the cost of an additional unit exceeds the income from it.

Step-by-step explanation:

In order to maximize production, the optimal point at which Hester should wash cars is the point where marginal revenue equals marginal cost. Marginal cost should not be above marginal revenue because it would mean that a marginal loss is being made.

At the 101st car, Hester would make a marginal loss of $0.05 because the cost of $10.05 to wash exceeds the revenue of $10.00 that she charges the customer. She should therefore not accept this or additional business because it will lead to her incurring losses.
