Sample Solution
The fundamental question for consideration here is, “How is management to choose from among these so many possible alternatives so as to maximize the present value of the expected future cash flows?” The answer to this question is indirect. Each potential alternative will have different cash consequences and change continuously with time. Therefore, analyzing the differences between available alternatives is essential to good decision-making. This analysis is called ‘differential’ or ‘incremental’ cash analysis. This basically gives managers an overlook of the advantages and disadvantages of the choice of alternatives. The final decision is to accept the alternative with the greatest net present value or cash flow, i.e. NPV
