The company is inclined to make the investment, but the managers are nervous because all of the cash flows and the MARR are approximate values. The capital investment is known to be within 5%. Annual expenses are known to be within 10%. The annual revenue, market value, and MARR estimates are known to be within 20%. a) (10pt) Conduct break-even analyses for each of all 5 variables (use the Excel solver if necessary), and for each analysis, assuming that all the other items are fixed as above, clarify whether we can say that the company should accept the project or we cannot say about that b) (10pt) Conduct sensitivity analyses by using the first (percentage change) method for each of all 5 variables (use the Excel solver if necessary) and rank those variables in descending order of sensitivity (from the most sensitive variable to the least sensitive variable). c) (10pt) Pick three most sensitive variables and conduct scenario analysis by setting three cases for each variable (using current estimate for the base case, and the bounds for the pessimistic and optimistic cases). Clearly mark the scenarios that results in the negative NPV
