Walt is mixing fruit punch for a party. he combines 1 gallon 2 quarts 3 pints of orange juice, 1 gallon 3 quarts 7 pints of pineapple juice, and 1 gallon 3 quarts 3 pints of ginger ale. what's the total liquid measure of the punch?

1 gal + 2 qt + 3 pts
1 gal + 3 qt + 7 pts
1 gal + 3 qt + 3 pts
add
3 gal + 8 qt + 13 pts

1 gal = 4 qts
1 gal = 8 pts
1 pt = 1/2 qt

13 pts =  6.5 qts
now we have 3 gal + (8 + 6.5) = 3 gal + 14.5 qts
12 qts = 3 gal
now we have : 6 gal + 2.5 qts or 6 gal + 2 qts + 1 pt <=== answer

Neither is the answer
