A company wants to increase the 10% peroxide content of its product by adding pure peroxide. If x liters of pure peroxide are added to 500 liters of its 10% solution, the concentration, C, of the new mixture is given byHow many liters of pure peroxide should be added to produce a new product that is 28% peroxide?
A fertilizer producer finds that it can sell its product at a price of p = 300 − 0.1x dollars per unit when it produces x units of fertilizer. The total production cost (in dollars) for x units is C(x) = 15000 − 125x + 0.025x 2 . If the production capacity of the firm is at most 1000 units of fertilizer in a specified time, how many units must be manufactured and sold in that time to maximize the profit?

x2-2(x-y)-z3 if x=2, y= -2 and z = -3
A company wants to increase the 10% peroxide content of its product by adding pure peroxide (100% peroxide). If x liters of pure peroxide are added to 500 liters of its 10% solution, the concentration, C, of the new mixture is given by : C = [x + 0.1(500)] / (x + 500). Then solve: How many liters of pure peroxide should be added to produce a new product that is 28% peroxide?.
