Three years ago, Zush company purchased a piece of equipment for $80,000 that was expected to have a useful life of 5 years with a $9000 salvage value. Increased demand necessitated an upgrade costing $30,000 one year ago. Technology changes now require that the equipment be upgraded again for another $25,000 so that it can be used for 3 more years. Its annual operating cost will be $48,000 and it will have a $19,000 salvage value after 3 years. Alternatively, it can be replaced with new equipment that will cost $68,000 with operating costs of $35,000 per year and a salvage value of $21,000 after 3 years. If replaced now, the existing equipment will be sold for $12,000. What is the AW of of the existing equipment at i=10% ? Less than ($50,000) between (50,000) to (60,000) between (40,000) to (50,000) between (30,000) to (40,000)
