Because no one should have to say, "I was never any good at math."

.................... liters X percent = total alcohol in subtance

solution a: x liters x (.65) = .65x

solution b: 10 liters x (.45) = 4.5

final solution: (x+10) x (.55) = .55x + 5.5

add solution a+b to get final solution

.65x + 4.5 = .55x + 5.5

.10x = 1.0

x = 10

There were 10 liters of the 65% solution
