After having viewed the video clips and worked through the extended reading, please respond to the below discussion prompt. You should post your initial response by the date indicated in the module calendar. Please be sure to reference your sources in appropriate APA formatting and to provide substantive evidence of any claims that you make. Where appropriate, include personal anecdotes, statistics, and references to additional reading or materials. After you have posted your initial response, visit the forum again over the coming days to read the responses of your peers. You should respond to at least two other students by asking them to elaborate on a point, providing a counter-argument, suggesting a topic for debate, or referring back to the extended reading or video clips. What is the difference between NPV and IRR? Are they related in any way? Which is superior and why? Must you choose one for decision-making or can you use both? Provide an example.
