You have two solutions one contains 40% acid, the other 10% acid. You require 10 gallons of a 20% solution. How much of the 10% should you use? I have to write an equation and solve.
one solution contains 40% alcohol. A second contains 60%. You need 20 L of 45% solution. How many L of the 40% should be used. I have to write an equation and solve
