A chemist has three different acid solutions. The first solution contains 15 % acid, the second contains 25 % acid, and the third contains 70 % acid. She created 108 liters of a 35 % acid mixture, using all three solutions. The number of liters of 70 % solution used is 2 times the number of liters of 25 % solution used. How many liters of each solution was used? The chemist used liters of 15 % solution, liters of 25 % solution, and liters of 70 % solution. Question Help: Video Submit
