Answer:
They can fill 15 gallons per hour.
Explanation:
In order to find the number of gallons, we first need to find the number of cups. We can find that by multiplying the number of juice boxes by the volume of a juice box.
300 * 0.8 = 240 cups
Next, we divide the number of cups by the number of cups in a gallon (16).
240/16 = 15 gallons
