The monthly revenue R achieved by selling
x wristwatches is figured to be The monthly cost C of selling x wristwatches is
(a) How many wristwatches must the firm sell to maximize revenue? What is the maximum revenue?
(b) Profit is given as P(x) = R(x) - C(x). What is the profit function?
(c) How many wristwatches must the firm sell to maximize
profit? What is the maximum profit?
(d) Provide a reasonable explanation as to why the answers found in parts (a) and (c) differ. Explain why a quadratic function is a reasonable model for revenue.
