Question 294648: A druggist has two solutions of alcohol. One is 25 % alcohol. The other is 45 % alcohol. He wants to mix these two solutions to get 36 ounces that will be 30 % alcohol. How many ounces of each of these two solutions should he mix together?
x+y=36, then x=36-y
.25x+.45y=36*.30
.25x+.45y=10.8
.25(36-y)+.45=10.8
9-.25y+.45y=10.8
9+.20y=10.8
.20y=1.8
y=9
x=27
