Hamada Equation-2

Situational Software Co. (SSC) is trying to establish its optimal capital structure. Its current capital structure consists of 30% debt and 70% equity; however, the CEO believes that the firm should use more debt. The risk-free rate, r_RF, is 4%; the market risk premium, RP_M, is 6%; and the firm's tax rate is 40%. Currently, SSC's cost of equity is 14%, which is determined by the CAPM. What would be SSC's estimated cost of equity if it changed its capital structure to 50% debt and 50% equity? Do not round intermediate calculations. Round your answer to two decimal places.
