To whom it may concern this is my situation, I hope I make myself clear.

Freccuntly in my finance class doing annuities, present value, future value, Bonds etc. I face upon Interest rate or Discount rate, and the teacher always give us the interest rate out of the blue and plus he's always saying that the Interest rate over the time it changes.

So, my question is, in the real world what is interest rate that am I going to work with? and where can I find it?

I'm too confused, help me please.

Than you.
