You decide to invest money to finance a project (software and/or hardware) you have genuinely developed during year-1 or year-2 of your engineering degree. Use the Net Present Value (NPV) formula to evaluate your investment, assuming it lasts five years. Consider how uncertainties may affect the NPV of your investment. In your own words, state and justify your assumptions and comment on your working. Marks will be assigned according to the quality of the presentation of your answer.
