Asked by Lucy

Last month, Bill's electric bill was $80.77. This month, Bill's bill was $69.06. What is the percent decrease?
0.01
0.16
0.15
0.14

my answer is 0.15
Answered by Ms. Sue
I don't think any of those answers is correct. The question asks for the percent decrease.

The percent decrease is 15%, not 0.15.

Answered by Lucy
yeah :/ and I don't know which I should be them
Answered by Ms. Sue
I'd tell your teacher that none of them is right. Tell him/her that the correct answer is 15%.

Answered by Steve
actually, I get 14%

The decrease was $11.71

11.71/80.77 = .1449

which is closer to .14 than .15

Pick 0.14 - 0.14 <u>is</u> 14%
just expressed as a decimal.

The wording is not optimal, but the two values are identical.
Answered by Ms. Sue
Steve is correct. It's 14%.
