Answer:
a. Post-tax interest rate on taxable bonds issued by the Coca-Cola Company =100%-22% =10*78%= 7.80
Dennis will choose Taxable bonds because it gives higher post-tax interest rate of 7.80% as against 7.50% on municipal bonds.
b. Post-tax interest rate on taxable bonds issued by the Coca-Cola Company
=100%-32% =10*68%= 6.80%
Dennis will choose municipal bonds because it gives higher tax free interest rate of 7.50% as against 6.80% on Taxable bonds.
c. Dennis will indifference when post-tax interest on Taxable bonds is equal to tax free interest on municipal bonds i.e 7.50%.
Let x% represent the expected tax rate.
=x% * 10%=7.50%
=10x%=7.50%
Divide both side by 10
=x%=7.5/10=0.75
=1-0.75=25%
At 25% tax rate, Dennis would be indifferent between the bonds.
