Answer: 3 Gallons
Explanation:
To find the total number of ounces she needs of juice we need to multiply the 22 cups by 12 ounces.
22 x 12 = 264
Now to find the number of quarts we need to convert the ounces into quarts by dividing by 32.
264 / 32 = 8.25
To find the number of gallons we need you have to convert it into gallons by dividing by 4.
8.25 / 4 = 2.0625
Because you cannot purchase .0625 of a gallon, we need to round up and purcahse 3.
