3(a) Assume that a company purchased a computer system (described below) one year ago and used it for one year. Purchase price plus installation cost amounted to $1 10,000. End of year Market value (xS1000) 4 75 65 45 35 According to its design, the expected service life of this system is 5 years (i.e., 4 years remain) Operating expenses were $11,000 the first year, increasing by $1,500 per year for the following years. That is, in year 2 of service, the operating cost becomes $11,000 + $1,500. This trend is expected to apply in the following years A new model is now available at a cost of S1 10,000 which includes installation charges. This unit is expected to have SO salvage after an 8 year life, and operating expenses are expected to be constant S13,000/year. Salvage value for any year before the 8 year life can be found by using the straight line method of depreciation. Should the new computer system be purchased now if the old can be sold at its market value? The need for computers will continue indefinitely, and the MARR is 8%
