A washing machine uses 40 gallons of water to wash 5 loads of laundry. The amount of water used varies directly with the number of loads of laundry. How many gallons of water would be used to wash 12 loads
Divide 40 by 5 to give you your gallons per load. Then multiply this result by 12 to get how many gallons you would use. Mathematically: 40gal/5loads = 8gal/load 12loads x 8gal/load = 96gal
