A restaurant manager has 2 liters of white wine that is 12% alcohol.
How many liters of white grape juice should he add to get a drink that is 10% alcohol?
:
Let x = amt of grape juice required
:
Write an equation using the amt alcohol, which remains the same (only the % changes)
.10(x+2) = .12(2)
.1x + .2 = .24
.1x = .24 - .2
.1x = .04
x = .04%2F.1
x = .4 liters of grape juice should be added
:
:
Check
.10(2.4) = .12(2)
.24 = .24
