Question

Before tax, and miscellaneous charges, Jason's cell phone bill is $100 per month plus $0.15 for every text message that he sends or receives. Which expression represents his cell phone bill for any given month?

Answer 1

0.15x + 100
x representing amount of text messages sent or received

Answer 2

`0.15x+100`.

Explanation:

Let x represent number of texts.

We have been given that Jason's cell phone bill is $100 per month plus $0.15 for every text message that he sends or receives.

Since cost of sending or receiving each text is $0.15, so cost of receiving and sending x texts would be
`0.15x`.

The total cost of bill would be fixed charge $100 plus cost of receiving and sending x texts. Therefore, Jason's cell phone bill would be
`0.15x+100`.
