Cooper electronics uses npv profiles to visually evaluate

Question

Cooper Electronics uses NPV profiles to visually evaluate competing projects. Key data for the two projects under consideration are given in the following? table:

                                       Terra                         Firma

Initial investment            $25,000                   $21,000

Year                              Operating cash inflows

1                                     $6,000                      $10,000

2                                     $6,000                      $6,000

3                                     $10,000                    $7,000

4                                     $11,000                    $8,000

Using these? data, graph, on the same set of? axes, the NPV profiles for each project using discount rates of 0?%,8?% and the IRR.
