The dishwasher will use 80 gallons of water to wash 10 loads of dishes.
Step-by-step explanation:
Given,
Water used for 4 loads of dishes = 32 gallons
Ratio of water used to load of dishes = 32:4
Let,
x represents the gallons of water required for 10 loads of dishes.
Ratio of water used to load of dishes = x:10
Using proportion
Ratio of water used to load of dishes :: Ratio of water used to load of dishes

Product of mean = Product of extreme

Dividing both sides by 4

The dishwasher will use 80 gallons of water to wash 10 loads of dishes.
