Apipe 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.
