You left the "Relevant equations" section blank. Why don't you start by populating it?
In particular:
What is the PDF of X? What is the conditional PDF of X given that X > a? What is the formula for the conditional expectation you are seeking, in terms of the conditional PDF?
By the way, is this really "pre-calculus" mathematics?
