Next time you need help with your school/course work, post the code you have written so far. pnsreee was nice enough to give you a suggestion, but in general we do not help people that have shown no effort, especially when the question is as basic as yours.

Agreed! You need to post the code you have tried. Also, correct me if I am wrong kevin, but I don't think that variables will interpolate inside of a regular expression, will they? (I could be wrong as I have never though of trying)

Yes, variables will interpolate inside of "m" and on the left side (the search side) of an "s" regular expressions, but not "tr". It is very common to use a scalar as a search pattern. To get variables to interpolate on the replacement side of an "s" regexp you have to use the "e" (as in eval) modifier.
