Dana intends to invest $30,000 in either a Treasury bond or a corporate bond. The Treasury bond yields 5 percent before tax and the corporate bond yields 6 percent before tax. Assuming Dana's federal marginal rate is 25 percent and her marginal state rate is 5 percent which of the two options should she choose? If she were to move to another state where her marginal state rate would be 10 percent, would her choice be any different? Assume that Dana itemizes deductions.
