Final answer:
The yield on the bond is 12% when the interest rates are higher than the market interest rate.
Step-by-step explanation:
The yield on the bond can be calculated by taking into account the interest payments and capital gains. In this case, the investor will receive the 1,000 face value of the bond, plus 80 for the last year's interest payment. The yield will be ((1,080 - 964) / 964) * 100% = 12%. When interest rates rise, bonds issued at lower rates will sell for less than face value, while bonds issued at higher rates will sell for more than face value.
