Hello, i stumbled across these two problems and wasn't entirely sure on how to do it, help is appreciated.
Find the future value FV accumulated in an annuity after investing periodic payments R for t years at an annual interest rate r, with payments made and interest credited k times per year.
1. R=$300, r=6%, t=12, k=4
2. R=$610, r=6.5%, t=25, k=12
Any help is appreciated, thanks!
