6)
at the end of first year ,
amount municipal bond offers = 10000*(1+0.091) =10910 $
amount treasury note offers = 10000*(1+(0.09/4))4*1 =10930.83 $
Treasury note is the better investment. At the end of first year it offers 20.83$ more than that of Municipal bond.
b)
amount invested P=10000, annual interesr rate r=9%=0.09,t =5 years, compounded quarterly =>n=4
amount after t years ,A=P(1+(r/n))nt
After 5 years,amount treasury note offers = 10000*(1+(0.09/4))4*5 =15605.09 $
