**Steve**, Thursday, March 1, 2012 at 3:25pmx liters of 18% acid has .18x liters of acid

y liters of 36% acid has .36y liters of acid

24 liters of 30% acid has .24*30 liters of acid

x+y = 24

.18x + .36(24-x) = .30*24

.18x + 8.64 - .36x = 7.2

.18x = 1.44

x = 8

so, 8L of 18% + 16L of 36% = 24L of 30%
