A bookstore is deciding what price it should charge for a certain book. After research, the store finds that if the book's price is p dollars (where 41 ≥ p), then the number of books sold per month is 123-3p. What price should the store charge to maximize its revenue?

Similar to previous posting

the number of books sold       123-3p

    revenue =   (123-3p) * p  = -3p^2 + 123p        max = -b/2a   =  -123/-6 = 20.5 dollars /book

 

[123-3(20.5)] * 20.5 = $ 1260.75 max revenue
