W38?0s wasts a capital structure that is 30% dels and 50% equity. Its corporate corbice federal and state income tax rate is 40%. West- Gas finds that it can finance in the domestic U.S. capital market at the following rates. Both debt and equity would have to be sold in multiples of $20 million, and these cost figures show the compo- nent costs of debt and equity, if raised half by equity and half by debt. A London bank advises West- Gas that U.S. dollars could be raised in Europe at the following costs, also in multiples of $20 million, while maintaining the 50/50 capital structure. Each increment of cost would be influenced by the total amount of capital raised. That is, if WestGas first bor- rowed $20 million in the European market at 6% and matched this with an additional $20 million of equity, additional debt beyond this amount would cost 12% in the United States and 10% in Europe. The same relationship holds for equity financing. a. Calculate the lowest average cost of capital for each increment of $40 million of new capital, where WestGas raises $20 million in the equity market and an additional $20 in the debt market at the same time. b. If WestGas plans an expansion of only $60 mil- Olion, how should that expansion be financed? c. What will be the weighted average cost of capital bis for the expansion
