The English Tea Company issues 8-year, zero coupon, $1000 par value bonds; these bonds pay no interest but can be redeemed for par value at maturity. To price these bonds competitively with bonds of similar risk, ETC determines that a yield of 7% should be offered. Calculate the value of the bonds now (with 8 years remaining until maturity) and for each year until maturity in 1-year increments (assuming no change in the required rate of return), then graph your results. Explain the behavior of the bond's value over time.
