The electricity meter on Donna's house

read 71,236.4 kwh at the beginning of

March and 73,196.2 kwh at the end of

March. She pays 7.4 per kwh. What is

the amount of her electricity bill for

March? Round to the nearest cent.

I came up with $145.03 Would you

please check to make sure I am correct?

No

(73 196.2 - 71 236.4)/7.4 =264.84 to the nearest cent

I added 71,236.4 + 73,196.2 divided by

7.4.

The possible solutions are:

A. $139.19

B. $145.03

C. $159.85

D. $195.98

One of these solutions is correct.

Please help, because I am wrong also.

Jake's process is not quite correct, and there's something wrong with his arithmetic!

73196.2 - 71236.4 = 1959.8

__Multiply__ that by .074, and you get your answer. B is correct.

You subtract to get the number of kwh used during the month. Then you multiply the number of kwh used by the number of cents, but you must use the $.074 to multiply by, not 7.4˘.

Congratulations, Veronica! You got it right the first time!
