Consider the three alternatives below, each with a 10-year useful life.  Solve the problem using benefit-cost ratio analysis.  If the MARR is 10%, which alternative should be selected?  Why are you selecting this alternative? Show me with your scratch work WHY you are choosing the alternative you are choosing.  Most points will be awarded for your justification via scratch work, NOT a correct multiple choice selection. Alt. A Alt. B Alt. C Initial Cost $800 $300 $150 Annual Benefit $142 $60 $33.50

If the B/C ratio for three alternatives A, B, and C are 2.8, 3.3 and 1.95 respectively, the best alternative is always “B” because it has the largest B/C ratio.

Suppose that we are analyzing the following six mutually exclusive alternatives using the rate-of-return method. The useful life of each alternative is 10 years, and the MARR is 10% per year.  All salvage values are assumed to be zero.               Alternative         First Cost      Net Yearly Benefits         Rate of Return                     A                     $  900                  $  150                             10.6%                     B                      1,500                      276                             13.0%                     C                      2,500                      400                               9.6%                     D                      4,000                      925                             19.1%                     E                       5,000                   1,125                            18.3%                     F                       7,000                   1,425                             15.6% It is also possible to “do nothing.”  Use rate of return analysis to select the best alternative.  Be sure to show all your comparisons, in the proper sequence, as outlined by the procedure illustrated in class. (NOTE:  You do NOT have to solve for exact ROR’s; try to approximate to the nearest 1 or 2%).  Which alternative should be selected? Justify your selection with your scratch work. Most points will be awarded for your justification via scratch work, NOT a correct multiple choice selection.

Catapult, Inc. is considering investing $10,000 in a new process to create a projectile made entirely of recycled high-density polyethylene (HDPE). They are concerned about the investment, however, because they are certain that five years from now they want to invest that $10,000 in a process to create a projectile made entirely of algae bi-product and they don’t want their capital tied up in any other investments.  Which analysis method should they use to determine if they should invest in the HDPE projectile process? Their MARR is 8%.
