For P500, 000, an engineer purchased a piece of equipment. He added another P40,000 to his budget for installation and other costs. The equipment's expected useful life is ten years. The salvage value is x% of the original cost. The book value at the end of five years using the straight line technique will be P300,500. What is the numerical value of x?
one factory manager bought a rare machine for $10 million. It is estimated that the sales value of the machine at the end of the first year will be $3 million and the machine will be worth $500,000 due to the demand by the antique dealers. The maintenance cost is expected to be $300,000 in the first 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. Calculate the economic life of this machine based on a 15% MCVO.

Assume the MARR is 10% per year for this analysis. A presently owned machine that was purchased 8 years ago for $450,000 is under consideration for replacement. It has an annual operating cost of $120,000 per year and a salvage value of $40,000 whenever it is replaced. The challenger has a first cost of $670,000, an expected annual operating cost of $94,000, and a salvage value of $60,000 after its 10-year economic life. The breakeven market value of the presently owned machine required to make the AW values of the two machines the same, if the presently owned machine is kept for 5 more years and then replaced with the challenger that has the same AW, is closest to: (a) $196,340 (b) $255,390 (c) $325,360 (d ) $394,770

The operating cost is expected to be $148,000 per year for the first 3 years and $210,000 for the next 3 years. The salvage value of the equipment is expected to be $140,000 for the first 3 years, but due to obsolescence, it won’t have a significant value after that. The interest rate is 10% per year. Determine the ESL and equivalent AW using tabulated factors.arrow_forwardThree years ago, Witt Gas Controls purchased 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 $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. If replaced now, the existing equipment will be sold for $9000. Calculate the annual worth of the defender at an interest rate of 10% per year. Answer: $ 54,025 Subject: ENGINEERING ECONOMICS Lesson: Decisions Under Certaintyarrow_forwardPlease answer by hand calculations not excel:A presently owned machine can last 3 more years, if properly maintained at a cost of $15,000 per year. 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. At i = 12% per year, perform a replacement study and determine whether the defender should be retained or replaced. Note:- Do not provide handwritten solution.

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.

- complete solution, thank youarrow_forwardA building supplies distributor purchased a gasoline-powered forklift truck 4 years ago for $8,000. At that time, the estimated useful life was 8 years with a salvage value of $800 at the end of this time. The truck can now be sold for $2,500. For this truck, average annual O&M expenses for year j have been Cj = $2, 000 + $400(j − 1) Now the distributor is considering the purchase of a smaller battery-powered truck for $6,500. The estimated life is 10 years, with the salvage value decreasing by $600 each year. Average annual O&M expenses are expected to be $1,200. If a MARR of 10% is assumed and a 4-year planning horizon is adopted, based on an annual worth cash flow approach should the replacement be made now?arrow_forwardA company that makes micro motion compact coriolis meters purchased a new packaging system for $600,000.

- Estimate the cost of ownership in terms of present worth for a machine based on the following data: Cost of machine = P120,000 Resale value in 8 years = P30,000 Maintenance, repair etc. = P5,000 per year and increasing P800 each year Rate of interest = 16%arrow_forwardDo not use the excel pv, pmt and fv functions for this question. Automobiles of the future will most likely be manufactured largely with carbon fibers made from recycled plastics, wood pulp, and cellulose. Last year (year 0), Carbon Manufacturing Company purchased a piece of equipment with $50,000 for research on this. The useful life of the machine is 12 years, at the end of which, the machine is estimated to have a $10,000 salvage value. The new machine generates annual revenues of $9,500. The annual operating and maintenance expenses are estimated to be $2,500. If the organization's MARR is 6%, calculate the following: 1. a) Draw the cash flow diagram for the project. 2. b) Calculate the present worth of the project. 3. c) Calculate the annual worth of the project. 4. d) Calculate the future worth of the projectarrow_forwardA machine purchased 3 years ago for $140,000 is now too slow to satisfy the demand of the customers. It can be upgraded now for $81,000 or sold to a smaller company Internationally for $42000. The upgraded machine will have an annual operating cost of $87,000 per year and a $32,000 salvage value in 3 years. If upgraded, the presently owned machine will be retalned for only 3 more years, then replaced with a machine to be used in the manufacture of several other product lines. The replacement machine, which will serve the company now and for a maximum of 8 years, costs $217,000. Its salvage value will be $52.000 for years 1 through 5: $20,000 after 6 years; and $10,000 thereafter. It will have an estimated operating cost of $45,000 per year.
