Answer and Explanation:
The computation is shown below;
Total value is
= Value of debt + Value of preferred stock + Value of equity
= $120,000 + $10,000 + $100,000
= $230,000
Now
Weight of debt is
= Value of debt Ă· Total value of firm
= $120,000 Ă· $230,000
= 0.52 or 52.17%
The Weight of preferred stock is
= Value of preferred stock Ă· Total value of the firm
= $10,000 Ă· $230,000
= 4.35%
And,
The Weight of equity is
= Value of equity Ă· Total value of the firm
= $100,000 Ă· $230,000
= 43.48%
