Step-by-step explanation:
N=30-3
N=27×2
N=54
PV=-930
Pmt=80/2
=40
FV= 1000
I/Y=4.34%
Coupon= 1000×0.08
= 80
YTM= 4.34×2
= 8.68%
The pretax cost of debt= 8.68%
To find the after tax cost of debt=?
After tax cost of debt=1-tax rate
= 1-0.35
= 0.65
YTM(1-tax rate)= 8.69(0.65)
= 5.65%
The after tax cost of debt=5.65%
