1.Jorge and Anita, married taxpayers, earn $160,000 in taxable income and $40,000 in interest from an investment in City of Heflin bonds. Using the U.S. tax rate schedule for married filing jointly, how much federal tax will they owe?

2.Melinda invests $300,000 in a City of Heflin bond that pays 6.4 percent interest. Alternatively, Melinda could have invested the $300,000 in a bond recently issued by Surething, Inc. that pays 8 percent interest with similar risk and other nontax characteristics to the City of Heflin bond. Assume Melindas marginal tax rate is 20 percent. What is her after-tax rate of return on the Surething, Inc. bond?
