Assume that your firm consists of Division $1(35$ percent of the firm$)$ and Division $2(65$ percent of the firm$).$ The capital structure for each of the divisions is the same as for the firm as a whole, $50\mathrm{.}0$ percent debt, at a before$-$tax cost of debt of $5\mathrm{.}4$ percent, and $50\mathrm{.}0$ percent equity. Also assume that the firm calculates the cost of equity for each division using a divisional beta, where Division $1$ has an unlevered beta of $1\mathrm{.}00,$ while Division $2$ has an unlevered beta of $1\mathrm{.}50.$ Finally assume that the risk$-$free rate is $4\mathrm{.}0$ percent and the expected return on the market is $15\mathrm{.}0$ percent $[$the firm uses CAPM for required returns$].$ Given this information, determine the average corporate$-$wide WACC for this firm. Use a tax rate of $40\%.$
