HELP! Namratha has the choice between investing in a city of Watkinsville bond at 4.5 percent or a Moe's, Inc. bond at 7 percent. Assuming that both bonds have the same nontax characteristics and that Namratha has a 32 percent marginal tax rate, in which bond should she invest? What interest rate offered by Moe's, Inc. would make Namratha indifferent between investing in the two bonds?
