OC userin Calculus·28 Aug 2019 (1 point) Suppose that a when a cell phone store charges 17S for a car charger, it sells 66 units. When it drops the price to 16S it sells 69 units. Assume that demand is a linear function of price. If each phone charger costs 1S to make, what price should the store charge to maximize its profit? If x is the number of times the price is reduced by one dollar. Find a function for total profit with respect to x. A negative value for x will mean the price is increased. f(x) = Price to maximize profit
