How many liters of a 6% acid solution plus how many liters of an 8% acid solution will make 12 liters of a 7.5% acid solution?
------
Similar problem:
-------
How many liters of a 20% acid solution and a 5% acid solution will make 25 liters of a 12% acid solution?
------
t = amt of 20%
f = amt of 5%
---
t + f = 25 (total solution)
20t + 5f = 25*12 = 300 (total acid)
-----
t + f = 25 (total solution)
4t + f = 60 ---- 2nd eqn divided by 5
--------------------------------------------- Subtract
-3t = -35
t = 35/3 liters
=============
f = 40/3 liters
