You are attempting to estimate the cost of capital for a new project. Your firm has a current debt-to-equity ratio of 2.4 and faces a corporate tax rate of 26%. Given that your equity is priced to yield 17.9% EAR and your debt yields on average 8.8% p.a., what is the estimated cost of capital for your firm?

Please report your answer so that if your WACC is 10% you enter the value 10 (without decimal notation, not 0.10).
