State-of-the-art digital imaging equipment purchased 2 years ago for $50,000 had an expected useful life of 5 years and a $5000 salvage value. After its installation the performance was poor, and it was upgraded for $20,000 one year ago. Increased demand now requires another upgrade for an additional $22,000 so that it can be used for 3 more years. Its new annual operating cost will be $27,000 with a $12,000 salvage after the 3 years. Alternatively, it can be replaced with new equipment costing $65,000, an estimated AOC of $14,000, and an expected salvage of $23,000 after 3 years. If replaced now, the existing equipment can be traded for only $7000. Use a MARR of 10% per year. (a) Determine whether the company should retain or replace the defender now. (b) Based on the poor experience with the current equipment, assume the person doing this analysis decides the challenger may be kept for only 2 years, not 3, with the same AOC and salvage estimates for the 2 years. What is the decision?
A 2000-pound, counterbalanced, propane forklift can be purchased for $30,000. Due to the intended service use, the forklift’s market value drops 20% of its prior year’s value in Years 1 and 2 and then declines by 15% until Year 10 when it will have a scrap/market value of $1000. Maintenance of the forklift is $500 per year during Years 1 and 2 while the warranty is in place. In Year 3 it jumps to $750 and increases $750 per year thereafter. What is the optimal life of the forklift using i = 10%?
A factory manager bought a rare machine for $10 million. of the machine The sales value at the end of the first year will be $3 million and the machine will be sold by antique dealers. It is estimated to be valued at $500,000 due to the Initial cost of maintenance Expected to be $300,000 in 3 years and double each year thereafter. In this way, the maintenance cost of the 4th year is $600,000, the maintenance cost of the 5th year is $1,200,000, etc. will be. Calculate the economic life of this machine based on the Minimum Attractive Efficiency Ratio of 15%.

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 $47,000, and it will have a $22,000 salvage 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.

- A critical machine in BHP Billiton's copper refining operation was purchased 7 years ago for $160,000. Last year a replacement study was performed with the decision to retain it for 3 more years. The situation has changed. The equipment is estimated to have a value of $8000 if "scavenged" for parts now or anytime in the future. If kept in service, it can be minimally upgraded at a cost of $43,000 to make it usable for up to 2 more years. Its operating cost is estimated at $22,000 in the first year and $29,000 in the second year. Alternatively, the company can purchase a new system, the challenger, that will have an AWC of $-51,000 over its ESL.

Its AOC is $31,000 per year. After 3 years, it can be sold for an estimated $9000. A replacement costs $80,000 with a $10,000 salvage value after 3 years and an operating cost of $19,000 per year. Different vendors have offered $10,000 and $20,000, respectively, for the current system as trade-in for the replacement machine.
