A commercial 3D printer is purchased for $ 380,000. The salvage value of the printer decreases by 35% each year that it is held. The cost to operate and maintain the machine the first year it is used is $ 12,500; these costs increase by $ 4,000 each year. What is the optimal replacement interval and minimum EUAC for the printer, assuming a MARR of 10% is used?
A replacement study is to be performed on certain pressing equipment in an industrial laundry. The challenging asset has a computed AW of –$41,000 at i = 15% per year for its anticipated 10-year life. The defender can be sold now for $32,000 or kept for a maximum of 4 more years. If kept, the data below will apply to the defender.

- A large city in the mid-West needs to acquire a street-cleaning machine to keep its roads looking nice year round. A used cleaning vehicle will cost $85,000 and have a $20,000 salvage value at the end of its five year life. A new system with advanced features will cost $150,000 and have $40,000 market value at the end of its five year life. The new system is expected to reduce labor hours compared with the used system. Current street-cleaning activity requires the used 'system to operate 8 hours per day for 20 days per month. Labor costs $50 per hour (including fringe benefits), and MARR is 12% per year. a. Find the breakeven percent reduction in labor hours for the new system. b. If the new system is expected to be able to reduce labor hours by 17% compared with the used system, which machine should the city purchase? c.

- 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%?arrow_forwardDd1.arrow_forwardIn the process of performing a replacement study, an engineer at a fiber optics manufacturing company has two options to reduce costs on a production line. The currently owned Robot X can be sold now for $82,000. If kept, it will have an annual M&O cost of $30,000, and salvage values of $50,000, $42,000, and $35,000 after 1, 2, and 3 years, respectively. A challenger, Robot Y, will have a first cost of $97,000, an annual M&O cost of $27,000, and salvage values of $66,000, $56,000, and $42,000 after 1, 2, and 3 years, respectively. Which robot should be selected if a 2-year study period is used at an interest rate of 12% per year? Solve by two ways: by hand and by spreadsheet.arrow_forward
