Question

A local water company charges a flat fee of $5 per month, plus $0.0007 per gallons, and $0.0009 per gallon for every gallon for every gallon in excess of 40,000. What is the water bill for a customer who uses 60,000 gallons of water a month?

Answer 1

Total cost= $51

Explanation:

Giving the following information:

Fixed cost= $5

From 0 to 40,000 gallons= $0.0007 per gallon

From 40,001 to infinity= $0.0009

We need to calculate the total cost for 60,000 gallons:

Total cost= 5 + 40,000*0.0007 + 20,000*0.0009

Total cost= $51
