Answer:
c. 6.86%
Step-by-step explanation:
The computation of the cost of debt is shown below:
Here we applied the rate formula
Given that
NPER = 30
PMT = $1,000 × 10% = $100
Assuming future value be $1,000
PV = $950
The formula is shown below:
= RATE(NPER;PMT;PV;FV;TYPE)
The present value should be in negative
After applying the above formula, the rate is 10.55%
Now the after tax cost of debt is
= 10.55% × (1 - 0.35)
= 6.86%
Hence, the correct option is c.
