The age that I selected is 21 years old. PLEASE SOLVE USING EXCEL FUNCTION AND SHOW HOW YOU DID IT AND WHERE YOU GOT THE NUMBERS FROM. Thank you!

Choose an age between 18 to 45 years that has not been chosen by any other student. Express your age in years only (Forget about month and day). 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 must pay to buy this bond? Face value of this zero-coupon bond is $10,000
