Answer 1:
The NPV method has been used to evaluate the relative attractiveness of the projects. Using the NPV function in financial calculator, the net present value (NPV) was found for each of the projects and the values are summarized below.
Project                   NPV                   NPV/Initial investment
1 $                        12,255.66                              0.02
2 $                      48,964.76                              0.10
3 $                      110,538.84                              0.55

As the NPV of the projects are positive, it means that all three of them are value-adding and can be undertaken....
