Your friend Raul told you about an exciting investment his bank is offering to select customers. It is a 15-year bond that provides the bearer with an interest payment every six months. The bond's face value is $7,500, and it has a coupon rate of 8.5%. How much is it worth today if the prevailing interest rate is 7.3% per year?
