A new anti-theft system incorporating MEMS technology is being economically evaluated separately by three engineers at Dragon

Question:

A new anti-theft system incorporating MEMS technology is being economically evaluated separately by three engineers at Dragon Technologies. The first cost of the equipment will be $75,000, 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 $10,000 per year. Susan states that this is too low and estimates $14,000, while Tyler estimates $18,000 per year. If the before-tax MARR is 8% per year, use PW to determine if these different estimates will change the decision to purchase the equipment. Perform the analysis

(a) By hand,

(b) Using a spreadsheet.

Salvage Value
Salvage value is the estimated book value of an asset after depreciation is complete, based on what a company expects to receive in exchange for the asset at the end of its useful life. As such, an asset’s estimated salvage value is an important...
MARR
