Suppose that annual income from a rental property is expected to start at $ per year and decrease at a uniform amount of $ each year after the first year for the -year expected life of the property. The investment cost is $, and i is % per year. Is this a good investment? Assume that the investment occurs at time zero (now) and that the annual income is first received at EOY one.

10            $855                                0.322                               $275.31

11            $800                                0.2875                              $230.00

12            $745                                 0.2567                            $191.24

Net Present Value                                                                  -$1,264.95

Since the net presnet value comes in negative so it is not beneficial for a company as it is not able to cover the initial investment

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
