Answer: 4.58%
Explanation:
The weighted average floatation cost is;
= (weight of debt * floatation for debt) + (weight of preferred stock * floatation for preferred stock) + (weight of common stock * floatation for common stock)
= (40% * 3.7%) + (4% * 4.8%) + (56% * 5.2%)
= 0.0148 + 0.00192 + 0.02912
= 0.04584
= 4.58%
