<u>Compound Interest</u>
This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.
The present value PV or the principal can be calculated with
Solving for R
Where Fa is computed by
We'll use the provided values but we need to convert them first to monthly payments
Thus, each payment is
