The punch has 7 1/2 gallons of juice mix for every 1 1/4 gallons of fresh fruit juice. how many gallons of juice mix are used per gallon of fresh fruit juice?

12,5 gallons

Step-by-step explanation: the fresh fruit juice represents the 8% of the mix juice

if there is 1 gallon of fresh fruit juice then the total mix juice must be 12,5 gallons

the relationship is the following:

7 1/2 gallon is equal to 15, 5 gallons

1 1/4 gallon is equal to 1,25 gallons

if 1, 25 gallons is 8% of the total mix juice if the new mix juice has 1 gallons of fresh fruit juice then 100/8 is the new amount of gallons of mix juice, this is: 12, 5 gallons.
