However, if it chooses project B, it will not have the opportunity to make a second investment. The following table lists the cash flows for these projects. If the firm uses the replacement chain (common life) approach, what will be the difference between the net present value (NPV) of project A and project B, assuming that both projects have a weighted average cost of capital of 12%?
