i got this problem wrong as well and can't figure out where the error is in my calculations.

corp has 7 million shares of common stock outstanding. the current share price is $86. book value is $5 per share. two bonds outstanding. first has face value of 70 million, a coupon rate of 9 percent, and sells for 96 percent of par. the second issue has a face value of 45 million, a coupon rate of 10 percent, and sells for 104 percent of par. the first issue matures in 24 years, the second in 6 years.

the most recent dividend was 5.80 and the dividend growth rate is 7 percent . assume that the overall cost of debt is the weighted average fo that implied by the two outstanding debt issues. both bond make semiannual payments and tax rate is 34 %.
