A chemist has three different acid solutions. The first acid solution contains 15% acid, the second contains 35% and the third contains 75 %. They want to use all three solutions to obtain a mixture of 95 liters containing 55 % acid, using 3 times as much of the 75% solution as the 35 % solution. How many liters of each solution should be used? The chemist should use liters of 75 % solution. liters of 15 % solution, liters of 35 % solution, and
