Answer:
on municipal bond after tax rate of return = 5 percent
on corporate bond after tax rate of return = 5.44 percent
Step-by-step explanation:
given data
rates of return = 5% = 0.05
rates of return = 6.4% = 0.064
tax bracket = 15% = 0.15
solution
first we get on municipal bond yield
municipal bond is tax exempt so
as on municipal bond there is no taxes is levied
so that here after tax rate of return will be as 5 percent
and
now we get after tax yield on corporate bond that is
after tax rate of return = rates of return × ( 1 - tax bracket ) .............1
after tax rate of return = 6.4% × ( 1 - 15%)
after tax rate of return = 0.064 × ( 1 - 0.15 )
after tax rate of return = 5.44 percent
