The price for obtaining a cubic reactor of 1.2 m length was 2000 $ in 2013 (and the instillation cost is 30% of its price). If it is wanted by an investor to obtain a new one of larger size (the double) this year and to insulate it using one layer of insulation material that was cost 7 $/m² in 2013 (knowing that the cost of workers was 4 $/m² in 2013). How much will be the cost to install this new reactor? Year M&S Material Worker Index Index Index 2013 323 360 1480 587 2021 1505 600
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?

- A theft-avoidance locking system has a first cost of $23,500, an AOC of $16,000, and no salvage value after its 3-year life. Assume that you were told the service provided by this asset would be needed for only 5 years. This means that the asset will have to be repurchased and kept for only 2 years. What would its market value, call it M, have to be after 2 years in order to make its annual worth the same as it is for its 3-year life cycle at an interest rate of 10% per year? Determine the market value M using factors. The market value M is $arrow_forwardA copper wire has a material cost that varies proportionally with the cross-sectional area (A) according to the expression $40,000 A. This wire has a lifetime of 30 years and a salvage value of $1500 A at that time. As the cross-sectional area of the wire increases, the resistance of the wire decreases such that the energy losses in the wire also decrease. The costs of these energy losses vary indirectly with the cross-sectional area according to the expression $70,000/A. Assuming an interest of 9%, what is the optimal value for this cross-sectional area? (Chapter 6- Annual Equivalent Worth Analysis)arrow_forwardA vertical oil well has been drilled and completed.

- To improve package tracking at a UPS transfer facility, conveyor equipment was upgraded with RFID sensors at a cost of $345,000. 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.

The types of fuel that can be used to ignite the boiler are natural gas, fuel oil, and coal. The cost of installation including all required controls is $40,000 for natural gas, $50,000 for fuel oil, and $120,000 for coal. In addition, the annual cost of fuel oil is $8,000 less than the annual cost of natural gas and $12,000 more than the annual cost of coal. The boiler is to be utilized for 20 years and interest rate is 8%. Using the most suitable approach, determine the best alternative. Is there any other consideration for the obtained result? As one way, please solve using either Cash Flow Analysis, Present Worth Analysis, or any other similar method.

- An expansion of the current BIM (Building Information Model) software has been proposed to First Financial, the building’s owner. A total installed cost of $120,000 is expected to generate additional savings of $40,000 per year for 10 years, after which time the software will be replaced with no salvage value. The annual M&O cost is expected to be $10,000 the first year and increase by an arithmetic gradient G between $1000 and $5000 per year thereafter. Determine if the expanded BIM is sensitive to gradient increases of $1000 (optimistic), $3000 (most likely), and $5000 (pessimistic) per year.
