A building supplies distributor purchased a gasoline-powered fork-lift truck 4 years ago for $8,000. At that time, the estimated useful life was 8 years with a salvage value of $800 at the end of this time. The truck can now be sold for $2,500. For this truck, average annual operating expenses for year j have been c_j = $2,000 + $400 (j - 1) Now the distributor is considering the purchase of a smaller battery-powered truck for $6,500. The estimated life is 10 years, with the salvage value decreasing by $600 each year. Average annual operating expenses are expected to be $1,200. If a MARR of 10% is assumed and a 4-year planning horizon is adopted, based on a cash flow approach should the replacement be made now
