Question 1093354: In the lab, Jessica has two solutions that contain alcohol and is mixing them with each other. She uses twice as much Solution A as Solution B. Solution A is
12%
alcohol and Solution B is
19%
alcohol. How many milliliters of Solution B does she use, if the resulting mixture has
86
milliliters of pure alcohol? Found 2 solutions by Boreal, josgarithmetic:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x=solution B ml
2x=solution A ml
.12(2x)+.19x=1.00(86), the 1.00 being 100% alcohol
.24x+.19x=86
.43x=86
x=86/.43=200 ml B at 19%=38 ml pure
2x=400 ml A @12%=48 ml pure
That sum is 86 ml
