Answer:
(B) 57.36 percent
Explanation:
Common Stock = 60,00,000x$15
              = $9,00,00,000
Preferred Stock = 20,00,000x$28
              = $5,60,00,000
Debt = 10,000x$1,000x109%
     = $1,09,00,000
Total Market Value = $5,60,00,000 + $1,09,00,000
                 = $15,69,00,000
Weight of Equity = [Market Value of Equity/Total Market Value]x100 Â
              = [$9,00,00,000/$15,60,00,000]x100
              = 57.36%
Therefore, The weight used for equity in the computation of Carrie D's WACC would be 57.36%
