Suppose that when a cell phone store charges 20$ for a car charger, it sells 115 units. When it drops the price to 19$ it sells 120 units. Assume that demand is a linear function of price. If each phone charger costs 1$ 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 a total profit with respect to.
A negative value will mean the price is increased.

f(x)= ?
Price to maximize profit = 22

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
