PLease solve problem.

Two-Stage Rocket paid an annual dividend of $1.25 yesterday, and it is commonly known that the firm's management expects to increase its dividend by 8.00 percent for the next two years and by 2 percent thereafter. If the current price of Two-Stage's common stock is $12.92, what is the cost of common equity capital for the firm? (Do not round intermediate calculations. Round answer to 0 decimal places, e.g. 15%.)
