I have to calculate the current fair value per share where

P/E = 20
growth rate = 10%
next year EPS = $2.50

Sounds like a question on a Rensselaer midterm exam...

Even if it's homework, we do not just answer problems for you. Since there's probably tons of questions just like this, I'm not sure why someone would think it's specifically from an exam, but if so, you should not even be asking about it. If it's homework, then post what you think or ask what you don't understand.
