A cell phone company sells about 500 phones each week when it charges $75 per phone. It sells about 20 more phones per week for each $1 decrease in prices. The company's revenue is the product of the number of phones sold and the price of each phone. What price should the company charge to maximize its revenue?
I've already figured out the equation: -20n^2+1000n+37500 but I need to find out the price that the company should charge (n).
