Question 1 of 5 > >> Save Answer estion 1 12 points Replacement analysis considers decisions about whether or not to buy new and more efficient equipment or to continue using existing equipment. Consider this economic analysis approach and provide BRIEF answers to the following questions. Answers should be clear, focused, and above all informative. You may use bullet points to organize your response. Limit your response to one to three sentences or phrases. Please identify each question by number in your response. For example, for each question listed below, your response should start Question 1) or 1) to indicate which question you are answering. Using this structure your responses to individual questions can be in any order (e.g. Question 2, Question 3, Question 1). Question 1) Consider a Defender - Challenger problem with a finite planning horizon where the Economic Service Life (ESL) of the defender is 2 years (AECDefender = $5,319) and the ESL for the challenger is 4 years AECChallenger = $6,900). Briefly describe when the defender should be replaced, assuming that the marginal cost to keep the defender for one additional year past it's ESL is $6,826. Question 2) Provide a brief overview of a replacement analysis decision by describing the analysis process and decision criteria. Assume that you are considering this decision using before-tax cash flows and an infinite planning horizon (ignore any tax effects in your analysis). Question 3) Consider the idea of sunk costs and relevant cash flows specifically. Provide a brief definition of this concept and describes its role in replacement analysis and decision making.
