a tank contains 10 gallons of a 6% salt solution. how much water must be evaporated so that an 8% salt solution will remain?
--------------------------------
Equation:
water - water = water
0.94*10 - 1*x = 0.92(10-x)
-----------
94*10 - 100x = 92*10 - 92x
-------
8x = 2*10
------
x = (1/4)10
------
x = 2.25 gallons (amt. of water to remove)
