A cell phone plan costs [unparseable or potentially dangerous latex formula] dollars each month, plus [unparseable or potentially dangerous latex formula] cents per text message sent, plus [unparseable or potentially dangerous latex formula] cents for each minute used over [unparseable or potentially dangerous latex formula] hours. In January Michelle sent [unparseable or potentially dangerous latex formula] text messages and talked for 30.5 hours. How much did she have to pay?

5t+10m+2000 = price in cents

5(100) + 10(30) + 2000 = 500+300+2000 = $28.00.

Wesley.
Just out of curiosity, are you asking these questions as doubts or as to show questions that are easy on the AMC 12?
I am a EDIT: SOPHOMORE (Summer has begun and Freshman year is OVER) and I am human. I don't think anyone can refute that - No Counterarguement!
If they do...well....i don't know if that's going to happen!

I believe he is just trying to post all the questions from the AMCs here so it is a resource with solutions.
