Answer:<em> </em><em>Therefore, the cost of preferred stock is </em><em>17.72%.</em>
Given:
Selling price (preferred stock) = $21
Annual dividend = 3.5%
Flotation costs = $1.25
We can compute the cost of preferred stock as:

Cost of preferred stock = 3.5 / ($21 - $1.25)
Cost of preferred stock = 17.72%
