Answer:
the firm's weighted average cost of capital is 4.09 %.
Explanation:
Weighted Average Cost of Capital (WACC) is the weighted return required by providers of long term sources of capital
WACC = Ke (E/V) + Kd (D/V) + Kp(P/V)
Ke = Cost of Equity
   = $1.50 /  $32 × 0.025
   = 0.11 %
E/V = Market Value of Equity
   = 44,000 × $32
   = $1,408,000
Kp = Cost of Preference stock
   = $ 9 / $ 72
   = 12.5 %
P/V = Market Value of Preference Stock
   = 7,500 × $72
   = $540,000
Kd = Cost of Debt
   = 8.3 % × 65%
   = 5.40 %
D/V = Market Value of Debt
   = $825,000 / $1,000 × $989
   = $815,925
WACC = 0.11 % × ($1,408,000/$2,763,925) + 12.5 % × ($540,000/$2,763,925) + 5.40 % × ($815,925/$2,763,925)
      = 4.09 %
