Question

ASAP PLEASE!

A particular dishwasher uses 4 gallons of water per load. Their advertising claims that hand washing the dishes uses 6 times as much water. According to this estimate, how many gallons of water would it save to wash 215 loads using the dishwasher instead of by hand?

Answer 1

Answer: 4,300 gallons of water

215 x 4 = 860 gallons of water using the dishwasher

215 x 6 x 4 = 5,160 gallons of water by hand

5,160 - 860 = 4,300 gallons of water saved by using the dishwasher.
