after tax cost of debt

After Tax Cost of Debt (COD) = 4.72 %

Cost of Equity = [Dc × (1 + G)] ÷ P + G

Where;

Dc = 1.95 $/share

G = 10 %

P = 50 $/share

Cost of Equity = [1.95 × (1 + 0. 1)] ÷ 50 + 0.1

Cost of Equity = 0.1429 (14.29 %)

Total Equity = 30 x 50 = 1,500 million $

Total Equity + Total Debt = 750 + 1,500 = 2,250 million $
