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
