1 Gallon = 16 cups.
So 3.76 gallons times 16 is equal to 60 cups. This eliminates A as an option for being our answer.
1 Gallon = 4 qt
3.75 gallons times 4 qt = 15 qt. This eliminates B ar our answer.
1 Gallon = 8 pt
So 3.25 gallons times 8 pt will give us 30 pt. In this case, our answer is not C because they are equivalent.
So our answer to this problem is D!
