Final answer:
To determine the tax rate at which you would be indifferent between investing in California municipal bonds and J and K Corp.'s bonds, calculate the after-tax returns of both options.
Step-by-step explanation:
To determine the tax rate at which you would be indifferent between investing in California municipal bonds and J and K Corp.'s bonds, you need to calculate the after-tax returns of both options.
Let's assume the tax rate is 'x'. For the California municipal bonds, the after-tax return would be 13.00% × (1 - x) = 0.13 × (1 - x). For J and K Corp.'s bonds, the after-tax return would be 19.50% × (1 - x) = 0.195 × (1 - x).
Set these two expressions equal to each other and solve for 'x':
0.13 × (1 - x) = 0.195 × (1 - x).
After solving this equation, the tax rate at which you would be indifferent between the two bonds is approximately 0.354, or 35.4%.
