Answer:
4.524%
Step-by-step explanation:
Jackson's marginal tax rate = 22%
after tax return of Sundial Incorporated bonds = 5.8% x (1 - 22%) = 4.524%
since municipal bonds are not taxed by the federal government, in order to compare the yields we must calculate the after tax return of corporate bonds. On the other hand, federal bonds do not pay state and local taxes.
