Answer :
Answer:
A. What is DeShawn's marginal benefit if he sells a basic detailing package?
- marginal benefit = marginal revenue - marginal cost = $75 - $40 = $35
B. What is the marginal cost of adding the engine detailing to the basic detailing package?
- $20
C. Should DeShawn continue to offer the engine detailing service?
- Yes. From an economic point of view, a firm maximizes its accounting profit when marginal revenue = marginal cost, and since DeShawn's marginal cost is still much lower than his marginal revenue, he should continue to offer it. From a marketing point of view, this premium service (it is more expensive) may be something that a certain percent of DeShawn's clients want and if he quitted that service he might lose the clients.
