XIII_BD:
How many gallons of distilled water must be mixed with 50 gallons of 30% alchohol solution, to obtain a 25% solution.

pls help me out here u guys....

astarmathsandphysics:
There are 15 gallons water to start.Suppose x gallons are added, the amount of solution is 50+x
(15)/(x+50)=0.25
15=0.25x+12.5
0.25x=2.5 so x=10
