Answer:
She should invest in a State of New York bond.
Explanation:
The return on a State of New York bond is 9.4%.
The return on a Surething Inc. bond is 12%.
Fergie has a 30% marginal tax.
A state tax will not be taxed. However, a corporate bond will be taxed.
After tax return will be
= [tex]12\% -\ (12\% \times\ 30\%)[/tex]
= [tex]0.12\ -\ (0.12\ \times\ 0.3)[/tex]
= 0.12 - 0.036
= 0.084
So, the return after tax will be 8.4%.
This is lower than the return on the state bond.
So, Fergie will invest in State bond.
