Question 1 General Lithograph Corporation uses no preferred stock. Their capital structure uses 35% debt (hint: the rest is equity). Their marginal tax rate is 22.72%. Their before-tax cost of debt is 6.56%. General Lithograph's stock has a beta of 2.63. The current risk-free rate is 2.29%, and the overall market is expected to return 9.64% over the long-run. What is General Lithograph's weighted average cost of capital (WACC)? Please enter without using the "%", but with two decimal places (in other words if you calculate 9.87%, then just enter 9.87).
