You can put this solution on YOUR website! How many liters of each of a 25% acid solution and a 85% acid solution must be used to to produce 70 liters of a 55% acid solution?
-----------------------
Equation:
acid + acid = acid
0.25x + 0.85(70-x) = 0.55*70
-----
25x + 85*70 - 85x = 55*70
-60x = -30*70
x = 35 liters (amt. of 25% solution needed)
------
70-x = 35 liters (amt. of 85% solution needed)
