Suppose you want to invest $10,000. You have two options: (1) Invest in California municipal bonds with an expected rate of return of 7.00%, or (2) invest in J and K Corp.’s bonds with an expected rate of return of 10.50%. Assume that your decision is based on a tax perspective. If everything else is the same for both bonds, at what tax rate would you be indifferent between these two bonds?
