A 10% acid solution is to be mixed with a 50% acid solution in order to get 120 ounces of a 20% acid solution. How many ounces of the 10% solution and 50% solution should be mixed?
------------------------------------
Equation:
acid + acid = acid
0.10x + 0.50(120-x) = 0.20*120
Multiply thru by 100 to get:
10x + 50*120 - 50x = 20*120
-40x = -30*120
x = 90 ounces (amount of 10% solution in the mix)
----------------------
120-x = 30 ounces (amount of 50% solution in the mix)
==================================
