Face Value Calculation?

This should be explained in your text book, but it sounds like a savings bond, so the value would be the $3,623.4767x500 =$1,811,738.30, the investor would make a 9.6% semi-annual return after 20 years. Which sounds like $34.79 a month for 20 years per unit held. It looks like they plan on paying out $172,926.87 in interest to it 500 investors for that period of time. I don't have the particulars in front of me nor the book, so this is only an educated guess. I would suggest you look it up or ask a clmate. Good luck
