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 p <= 40), then the number of books sold per month is 120-3p. What price should the store charge to maximize its revenue?

[130-5(13)] (13) = $845   max revenue.

Step-by-step explanation:

If the number of books sold = 130-5p      then revenue will be   (130-5p)p = -5p^2+130p

the maximum can be found by graphing or by the fact that the max will be   -b/2a   =   -130/-10 = 13 dollars/book

[130-5(13)] (13) = $845   max revenue.

probability for j is 1/4

while

a is 1/6

i can't solve unless i know what the line is
