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.

QUESTION 3 Because it fumes at room temperatures, hydrochloric acid creates a very corrosive work environment. A machine working in that environment is deteriorating quickly and can be used for only one more year, at which time it will be scrapped with no salvage value. It was purchased 3 years ago for $88,000, and its operating cost for the next year is expected to be $57,000. A more corrosion-resistant challenger will cost $212,000 with an operating cost of $55,000 per year. It is expected to have a $50,000 salvage value after its 10- year ESL. At an interest rate of 11% per year, what minimum replacement value would render the challenger attractive? The Replacement Value, (in $)
The Delta firm intends to buy a device called machine X. Machine X would cost $25,000 and have little salvage value after 10 years of use. The machine is anticipated to bring around $10,000 annually. Do the simple payback period calculation.
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.

Hydrochloric acid, which fumes at room temperatures, creates a very corrosive work environment. A mixing machine working in this environment is deteriorating fast and can be used for only 1 more year, at which time it will be scrapped. It was purchased 3 years ago for $88, 000 and its operating cost for the next year is expected to be $67,000. A more corrosion-resistant challenger will cost $226,000 with an operating cost of $54,000 per year. It is expected to have a $ 60,000 salvage value after its 10-year ESL. At an interest rate of 15% per year, what minimum trade - in value will make the challenger economically attractive? On equating the AW values of the defender and the challenger, to calculate the minimum trade - in value of the challenger, the spreadsheet tool that should be used is GOAL SEEK. The minimum trade - in value that will make the challenger economically attractive will be $54, 703.96. Give correct answer Hydrochloric acid, which fumes at room temperatures, creates a…
