Starting off with 3600 gallons of water, we know that this needs to be changed to quarts, which to do this you multiply it by 4.
3600 x 4 = 14400
This now shows how many quarts of water are wasted every year, but we need it in months. To do this, we divide by twelve because there are 12 months in a year.
14400 / 12 = 1200
This leads you with the answer of 1200 quarts of water being wasted every month.
