Suppose that a 12-year bond with a face value of 1000 dollars pays semiannual coupons at a rate of 4.2 percent per half year. The issuer of the bond has the option to redeem it at the time of the 16th coupon for 2200 dollars, or at maturity for 2000 dollars. Find the price that will guarantee an investor a yield rate of at least 12.9 percent convertible semiannually, regardless of when the bond is redeemed
