Express your age in years only (Forget about month and day, for example if you are 22 years and 5 months and 15 days, then use 22 years. If you are 22 years and 6 month and 10 days, then use 23 years old). Assume you buy a zero coupon bond that matures when you get to retirement age of 67. If the yield of this bond is 4% compounded semiannually, how much you have to pay to buy this bond? Face value of this zero coupon bond is $10,000.
