You can put this solution on YOUR website! --- percent ---------------- Amount
Solution I 32 ---------------- 11 liters
Solution II 11 ---------------- x liters
Mixture 22 ---------------- 11 + x liters
32 * 11 + 11 x = 22 ( 11 + x )
352 + 11 x = 242 + 22 x
11 x -22 x = -352 + 242
-11 x = -110
/ -11
x = 10 liters Solution II
