Two hundred liters of a 75% acid solution is obtained by mixing a 90% solution with a 50% solution. How many liters of each?

200 liters of 75% = .75 (200) = 150 gallons of acid

.90 x + .50(200-x) = 150

.9x + 100 - .5x = 150

.4x = 50

x = 90% solution = 125 gallons

200-x = 50% solution = 200-125 = 75 gallons of 50% solution
