Answer:
b. 8.225%
Explanation:
The rate formula will be used to solve this question.
Please note that the NPER represents the time value.
Where;
Present value is $754.08
Let's assume that the face value is $1,000
PMT= 1,000 x 7.25% ÷2
=$36.25
NPER= 9 years x 2
= 18 years
The formulae is therefore
Rate(NPER,PMT,-,PV,FV)
The value of the present value is negative.
a. The pretax would therefore be 11.75%
b. After tax cost of debt would be ;
Pretax cost of debt x (1 - tax rate)
11.75% x (1 - 30%)
11.75% x (1 - 0.03)
=8.225%.
