If compounding is monthly, find the effective monthly interest rate, the ef$-$

fective annual interest rate, and the nominal interest rate that will make the

following values of $F$ and A equivalent for the values $n$ shown.

a$.F=$$$5,000$;$A=$$$500$ annual payments; $n=8$ years.

b$.F=$$$16,500$;$A=$$$299$ monthly payments; $n=4$ years.

c$.F=$$$18,000$;$A=$$$250$ quarterly payments; $n=13$ years.

d$.F=$$$36,000$;$A=$$$800$ semiannual payments; $n=12$ years.
