(a) (b) (c = a × b)

Debt $380,000 107% $406,600 13.45%
Preferred stock 6,900 $91 $627,900 20.77%
Common stock 28,000 $71 $1,988,000 65.77%
Total $3,022,500
Now the WACC is
Particulars Cost Weight Weighted cost
Debt 4.78% 13.45% 0.64%
Preferred stock 7.69% 20.77% 1.60%
Common stock 13.40% 65.77% 8.81%
WACC 11.05%
Working Notes:
Cost of debt = 7.84% × (1 - 39%)
= 4.78%
Cost of preferred stock = Dividend ÷ current price
=(7% × 100) ÷ 91
= 0.07692
= 7.69%
