A long term FedEx bond that pays a coupon of 4.81% per year with a maturity of 2039. If the current price of the bonds is expressed as $96.68 (this is the % of par of 1000), what is the yield to maturity of the bonds? NOTE: the answer is approximate so your answer may be slightly off but still correct. (Assume year is 2021 so 18 years or 36 six month periods.) Express your answer as a decimal (5.83% is .0583).
