more a calclus question with an economics application. First, set the equation for total revenue TR. TR is simply price times quantity -- P*Q. Multiply your equation by P.

P*Q = 9P-.5P^2 = TR

Next, find the first derivitive wrt to P. TR' = 9-P. Find the P such that TR'=0. Obviously P=9. This is the revenue (not profit) maximizing price.
