13. 5.43 Consider the cash flows for two types of models given in Table 25.43 Table P5.43 4:19 PM + Fit to pas n 0 - Model A $8,000 Model B -$15,000 $3,500 $10,000 $3,500 $10,000 $3.500 Table P5.43 Full Alternative Text Both models will have no salvage value upon their disposal (at the end of their respective service lives). The firm's MARR is known to be 1296 1. Notice that the models have different service lives. However, model A will be available in the future with the same cash flows, whereas Model B is available at one time only. If you select model B now, you will have to replace it with model A at the end of year 2. If your firm uses the present worth as a decision criterion, which model should be selected, assuming that the firm will need either model for an indefinite period? 2. Suppose that your firm will need either model for only two years. Determine the salvage value of model A at the end of year 2 that makes both models indifferent (equally likely)
