Answer:
Option C is the correct answer,$60000 after tax cost of debt and $70000 cost of preferred stock.
Explanation:
The after tax cost of debt is the interest payable multiplied by(1-t), where represents the tax rate which is 40%
Interest is $1000000*10%=$100000
$100000(1-0.40)=$60000
Since preferred stock is not tax deductible, the cost of preferred stock is the yearly dividends.
Dividends on preferred stock=7%*$1000000
=$70000
As a result, the after tax cost of debt is $60000 and $70000 for preferred stock.
