You are considering two projects that are independent. Your firm has access to $570,000 only. The cost of capital for both projects is 10%. Project A costs $180,000 and generates cash flows of $36,000 per year for 15 years. Project B costs $300,000 and generates cash flows of $50,000 per year for 15 years. A7. The reason why the relative ranking for these two projects changes depends on (a) their scale differences. At very low rates of interest NPVA> NPVB (b) their future cash flow volatilities. At very high rates of interest NPVA NPVA (e) their timing differences. At very low rates of interest NPVA
