The Bridgeport water department has a monthly service charge of $13.20 and a usage charge of $1.42 for every 100 cubic feet of water. Which of the following equations can be used to determine the monthly water bill of a Bridgeport resident?


(Let x represent the amount of water used in hundreds of cubic feet and y represent the monthly cost.)


A. y = 1.42x - 13.20

B. y = 14.62x

C. y = 1.42x + 13.20

D. y = 0.0142x + 13.20

Answer 1

c

Explanation:

It is measured in the same unit as the original unit, so x will be 1.42x

Add the service charge as it is a constant addition, and we end up with:

y = 1.42x + 13.20
