An airline sells a 3 day vacation package. Sales from this vacation package can be modeled by the quadratic function s(p) = -40p^2 + 32000p. Sales are dependent on on the price p, of the package. If the price is set too high, the package won't sell, but if the price is too low, prospective buyers will think it is a scam. At what price, p, does the company have the greatest revenue?
