A wireless phone plan cost eric $35 for one month of service. If Eric used 450 text messages and was charged an contract fee of $12.50, how much did he pay per text

Sounds like a homework question.

We don't do homework on this site. This is your work, and you have to put in the effort.

So post the equation you'd use to figure this out, and post your answer. We'll critique your work, but we won't do it for you.

If Eric is like my daughter then he doesn't actually pay for the text, his parents do.

Good point. :)
