1、“Investment fi nancing is by a $2 million loan at a fi xed interest rate of 10% per year”；fficeffice" />

2、“The real weighted average cost of capital of OKM Co is 7% per year”。

但是在计算NPV的时候不需考虑每年的利息，答案的解释是“Interest payments have been included in the investment appraisal, but these are allowed for by the discount rate used in calculating the net present value”。

请问这怎么理解？
