For Chemistry class you need to mix 10% and 30% acid solutions. How many liters of each type should be mixed in order to make 20L of 15% acid solution.
+37157 20 L final volume
ingredients = final product
10% volume = x
30% volume = 20 - x
.10 (x) + .30 ( 20-x) = .15 (20) solve for x the 10% volume needed then 30% volume = 20 - x liters
