Compute the Payback Period, Net Present Value and Internal Rate of Return for each of the three investment options.  Submit the recommendation as a one-page Word document along with an Excel file showing your work as partial credit will be rewarded.  My recommendation is to read the description of each option to determine relevant costs and benefits (those that change based on whether you undertake the project or not).  Do not consider costs that are incurred regardless of your decision or costs that occurred in the past (sunk costs).  Add the relevant costs to the yearly cash flows provided.  Explain your reasoning so that I may award you partial credit and offer better feedback.
