Answer:
1.3125 gallons would have been wasted in 7 days
Step-by-step explanation:
mathematically, there are 0.0625 gallons in a measuring cup
So within the time frame, 0.0625 of liquid was lost
The time frame is 8 hours difference
The number of hours in 7 days will be;
7 * 24 = 168 hours
0.0625 gal in 8 hours
x gal in 168 hours
x * 8 = 168 * 0.0625
8x = 10.5
x = 10.5/8
x = 1.3125 gallons
