Each machine is capable of performing the same task in a given amount of time. Assume the minimum attractive rate of return (MAR) is 8%. The following data are to be used in your analysis. Machine Y $8,000.0 $ 150.00 $2,000.00 12 Machine X $5,000.00 First Cost Annual Maintenance Cost0.00 Salvage value Estimated life, in years S0.00 Which machine would you choose? Base your answer on annual cost. Chapter 5 A firm is considering three mutually exclusive alternatives as part of a production improvement program. The alternatives are: $10,000 $15,000$20,000 Installed Cost Uniform Annual Benefit Useful life, in years S 1,625$ 1,530 S 1,890 20 10 For each alternative, the salvage value at the end of its useful life is zero. At the end of ten years, A could be replaced with another A with identical costs and benefits. The minimum attractive (MARR) is 6%, which alternative should be selected? .
