**drwls**, Sunday, November 14, 2010 at 8:29amLet x be the price.

The number sold is

N = 80 - 5(x -12)= 140 -5x.

The revenue is 140x -5x^2 dollars.

Try completing the square, since you probably don't know how to use differential calculus yet. Maximum revenue ($980) is at a price where

140 - 10x = 0

x = $14

At a price of $13 or $15, the revenue is $975.
