terry goofed up when making 10 gallons of punch. He made a punch mix that was 20% juice concentrate instead of the usual 30% How much pure juice does he have to add to the 10 gallons to bring it up to 30% punch
Answer provided by our tutors
in 100 gallons you have 20% punch
in x gallons you might have 30% punch
so x=(100*30%)/20%=300/20=15
so you must add 15 gallons of pure juice
