Answer:
weight % of equity = 76.05%
weight % of preferred stock = 5.70%
weight % of debt  = 18.25%
Explanation:
calculation for equity:
total number of equity is 100,000
market price of stock = 40
so total value of stock = 40 × 100,000 = 4,000,000
calculation for preferred stock:
total number of share is 10,000
market price of stock = 30
so total value of stock = 30 × 10,000 = 300,000
calculation for debt:
total number of bond is 1,000
market price of  bonds = 960
so total value of stock = 960 × 1,000 = 960,000
total value = 4,000,000 + 300,000 + 960,000 = 5,260,000
Calculation of weight percentage
weight % of equity  =[tex]\frac{4,000,000}{5,260,000} = 0.7604 = 76.04%[/tex]
weight % of preferred stock  [tex]= \frac{300,000}{5,260,000} = 0.0570 = 5.70[/tex]%
weight % of debt  [tex]= \frac{960,000}{5,260,000} = 0.1825 = 18.25\%[/tex]
