1. The problem statement, all variables and given/known data The demand function for a product is modeled by p=56e^-0.000012x Where p is the price per unit (in dollars) and x is the number of units. What price will yield a maximum revenue. 2. Relevant equations 3. The attempt at a solution Ok so i tried taking the derivative to start off with. it is obviously an awkward problem. The derivative i found, and this may be wrong is (6.72 x 10^-4)e^-1.000012x if that is right, where from here?
