23. Two years ago, a company issued $20 million in long-term bonds at par value with a coupon rate of 9 percent. The company has decided to issue an additional $20 million in bonds and expects the new issue to be priced at par value with a coupon rate of 7 percent.

B. 4.8%. C. 5.4%. 两年前发行的20M就不考虑在内了吗？

2. Which of the following statements is correct? A. The appropriate tax rate to use in the adjustment of the before-tax cost of debt to determine the after-tax cost of debt is the average tax rate because interest is deductible against the company's entire taxable income. B. For a given company, the after-tax cost of debt is generally less than boththecost of preferred equity and the cost of common equity. C. For a given company, the investment opportunity schedule is upward sloping because as a company invests more in capital projects, the returns from investing increase. B的说法严谨吗？也有债券融资成本很高的公司吧？
