Explanation:

Weighted average cost of capital WACC determines firms cost of capital. It includes all sources of finance which are included in firms capital structure. The WACC is calculated with given formula:  

WACC = E/V Re + D/V * Rd (1 - T)

Re = cost of equity

V = Firms Market value of Debt and Equity

Rd = Cost of debt

E = market value of equity

D = market value of debt

T = Marginal Tax rate

WACC = 14.7 * 1 / 1.45 + 8.1 * 0.45 / 1.45 (1 - .34)

WACC = .1013 + 0.0165

WACC = 11.78%
