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?
An $80,000 baling machine for recycled paper was purchased by the XYZ company two years ago. The current MV of the machine is $50,000, and it can be kept in service for seven more years. MARR is 12% per year and the projected net annual receipts (revenues less expenses) and end-of-year market values for the machine are shown below. When is the best time for the company to abandon this project?

A remotely situated fuel cell has an installed cost of $2,000 and will reduceexisting surveillance expenses by $350 per year for eight years. The border security agency’s MARR is 10% per year. Solve, a. What is the minimum salvage (market) value after eight years that makes the fuel cell worth purchasing? b. What is the fuel cell’s IRR if the salvage value is negligible?
8 years ago a company installed a robot that today has a market value of $ 60,000 and each year it drops $ 2000. For example, at the end of the first year the market value will be $ 58,000 and so it continues to decline. Maintenance costs for the next 4 years are estimated at $ 3000 this year and increasing 10% each year. Determine the marginal cost of extending the service for one year, for the next 4 years if the MARR is 12%. Fill in the blanks with the results. Calculate: a) The loss of market value in year 1 is $ b) Loss in interest in year 1 $ c) The Marginal Cost in year 1 is Show all the procedure for your answer thank you
A portable concrete test instrument used in construction for evaluating and profiling concrete surfaces (MACRS-GDS 5-year property class) is under consideration by a construction firm for $24,000. The instrument will be used for 6 years and be worth $1,000 at that time. The annual cost of use and maintenance will be $11,000. Alternatively, a more automated instrument (same property class) available from the manufacturer costs $28,500, with use and maintenance costs of only $7,500 and salvage value after 6 years of $2,500. The marginal tax rate is 25%, and MARR is an after-tax 12%.Determine which alternative is less costly, based upon comparison of after-tax annual worth. select an alternative Show the AW values used to make your decision:Alternative 1: $enter a dollar amount Alternative 2:
Your company is considering the introduction of a new product line. The initial investment required for this project is $500,000, and annual maintenance costs are anticipated to be $45,000. Annual operating costs will be directly proportional to the level of production at $8.50 per unit, and each unit of product can be sold for $65. If the MARR is 15% and the project has a life of 5 years, what is the minimum annual production level for which the project is economically viable? Use the AW method.
: A machine was purchased and installed 6 years ago for $50000 with a useful life of 10 years. The salvage value is now $5500 and decreasing at a rate of $500 per year. The machine has a maintenance cost of $2000 per year. Assuming a 12.4% MARR, should the company replace the machine this year with a potential new machine that has a EUAC of $3000 per year?

A piece of equipment has a first cost of $150,000, a maximum useful life of 7 years, and a market (salvage) value described by the relation S = 120,000 – 17,000k, where k is the number of years since it was purchased. The salvage value cannot go below zero. The AOC series is estimated using AOC = 60,000 + 7,000k. The interest rate is 14% per year. Determine the economic service life and the respective AW. The economic service life is ...... year(s) and the AW value is ........
The city of Oak Ridge is considering the construction of a four kilometer (km) greenway walking trail. It will cost $1,000 per km to build the trail and $300 per km per year to maintain it over its 20-year life. If the city’s MARR is 7% per year, what is the equivalent uniform annual cost of this project? Assume the trail has no residual value at the end of 20 years.
A factory purchased new heavy-duty equipment and intended to be used for 4 years. The information is given below. At MARR of 22% per year, determine the capital recovery (CR). Instruction: Enter a negative value for CR. First Cost, $ -275,000 Annual cost, $/year 5,000 Salvage value, $ 125,000 Life, years 4
A potential project is currently under review. An initial investment of $87,000 would be necessary for equipment. The annual revenues and expenses are expected to be $40,000 and $19,000 each year, respectively, over the 6-year project period. The salvage value of the equipment at the end of the project period is projected to be $17,000. Assume a MARR of 9%. Find the AW (directly - do not convert from either FW or PW - to the nearest cent).
$250,000 is invested in equipment having a salvage value equal to $250,000(0.80n) after n years of use. O&M costs equal $60,000 the first year and increase $8,000 per year. Based on a MARR of 10%, what are the optimum replacement interval and minimum EUAC?
