Uh, okay? And how is repeating that in any way useful. Pengwuino didn't expect you to provide an entire solution, because you wouldn't be here in the first place if you had one. Showing effort means show us what you've tried.

This shouldn't be that hard. The present value of any type of quantity has a very specific formula.
