The City of Killeen utilities charges for water usage per gallon on a monthly basis as listed below.

Up to 500 gallons ($0.15/gallon)

More than 500 gallons - 1000 gallons ($0.33/gallon)

How much will Mrs Lapid pay if she uses 795 gallons in a particular month?

Answer 1

$172.35

Explanation:

The computation of the amount need to pay for 795 gallons is shown below

Up to 500 gallons it charges $0.15 per gallon

And, for more than 500 gallons till 1000 gallon, it charges $0.33 per gallon

So for 795 gallon, the total amount would be

= 500 × $0.15 - (795 - 500) × $0.33

= $75 + $97.35

= $172.35
