Question

Assume the base unit of water is 555 gallons and the cost per unit is $1.74. How much money will be saved in a month by a family who conserves 8000 gallons of water per month?

Answer 1

1) Gathering the data

555 gallons ----- $ 1.74

2) If 8000 gallons could be spent

If a Family conserves 8000 gallons this family would not have an expense of?

Let's set a proportion for that:

555 g-----$1.74

8000g ---x

555x =13920 Dividing both sides by 555

x=25.08

If a family conserves 8000 gallons of water. They save $25.08 per month assuming that $1.74 is equal to 555 gallons of water.
