ABC Telecom has to choose

between two mutually exclusive projects. If it chooses project A$,$

ABC Telecom will have the opportunity to make a similar investment

in three years. 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 $12\%?$
