Anew cross-country, trans-mountain water pipeline needs to be built at an estimated first cost of $200,000,000. the consortium of cooperating com- panies has not fully decided the financial arrange- ments of this adventurous project. the wacc for similar projects has averaged 10% per year. (a) two financing options have been identified. the first re- quires an investment of 60% equity funds at 12% and a loan for the balance at an interest rate of 9% per year. the second option requires only 20% eq- uity funds and the balance obtained by a massive international loan estimated to carry an interest cost of 12.5% per year. which financing plan will result in the smaller average cost of capital?
