Gabe Amodeo, a nuclear physicist, needs 60 liters of a 40% acid solution. He currently has a 30% solution and a 60% solution. How many liters of each does he need to make the needed 60 liters of 40% acid solution?

.30 x     +   .60 ( 60-x)    = .40 (60)     solve for x = 30 % amount    then   60% amount = 60 - x
