Answer:
The firm's cost of preferred stock is 9.10%
Explanation:
The cost of preferred stock with the flotation of 5% would be the dividend payable by the preferred stock divided by the adjusted current market price(adjusted for flotation cost)
The dividend per year is $8
The adjusted price of the stock=$92.50*(1-f)
where f is the flotation cost in percentage terms i.e 5%
adjusted price of the stock is =$92.50*(1-5%)=$ 87.88
Cost of preferred stock=$8/$87.88*100 = 9.10%
