A new antitheft system incorporating MEMS technology is being separately evaluated economically by three engineers at Dragon Technologies. The first cost of the equipment will be $90,000, and the life is estimated at 6 years with a salvage value of $9000 The engineers made different estimates of the net savings that the equipment might generate. Jacob made an estimate of $9,000 per year Susan states that this is too low and estimates $18,000, while Tyler estimates $21.000 per year before tax If the MARRIS X per year use PW to determine if these different estimates will change the decision to purchase the equipment, The present worth of the pessimistic estimate is $ * The present worth of the most likely estimate is $ The present worth of the optimistic estimate is $[ The equipment purchase by the pessimistic estimate is not justified The equipment purchase by the most likely estimate is not justified The equipment purchase by the optimistic estimate is justified
