A pipe is leaking at 1.5 cups per day. About how many gallons per week is the pipe leaking "hint"1 gal=16 cups

Water lost from pipe per day = 1.5 cups

Water lost from pipe per 7 days = 1.5*7 cups

= 10.5 cups

16 cups = 1 gallon

10.5 cups = 16/10.5 gallon

=0.656 gallon

So the pipe is leaking about 0.656 gallon per week.
