Answer:
d. 8.125%.
Step-by-step explanation:
The computation of the after tax cost of debt is shown below:
Given that
NPER = 13 × 2 = 26
PMT = $1,000 × 8.5% ÷ 2 = $42.50
Assume future value would be $1,000
Present value is $746.16
The formula is given below:
= RATE(NPER;PMT;-PV;FV;TYPE)
After applying the above formula, the rate is
= 6.25% × 2
= 12.50%
Now the after tax cost of debt is
= 12.50% × (1 - 0.35)
= 8.125%
Hence, the correct option is d. 8.125%
