Question 747959: lisa will make punch that is 25% fruit juice by adding pure fruit juice to a 2-liter mixture that is 10% pure fruit juice. how many liters of pure juice does she need to add?
You can put this solution on YOUR website! The current non-juice volume is .9 x 2l or 1.8 l
A 25% mix means 1.8 = 75% of new mix and 2.4 is total volume.
.6l of juice total, but so far there's .2l juice, so add .4l juice.
We go from .2/2 (10%) to .6/2.4 (25%)
