Busy Life Of Santa Claus!

Algebra Level 1

Here is a difficult word problem I am struggling with:
8-year-old Samantha visited Santa at a local department store. He gave her this riddle:

I started working at 15.
I spent 1/4 of my working life in a factory.
I spent 1/5 of my working life in an office,
and I spent 1/3 of my working life as a school caretaker.
For the last 13 years of my working life I've been Santa Claus.
How old am I?
