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?

The Ajax Corporation has an overhead crane that has an estimated remaining life of 10 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 10% per year in evaluating investment alternatives. Should the company replace the old crane?
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.

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.

- Michelin is considering going ‘‘lights-out’’ in the mixing area of the business that operates 24/7. Currently, personnel with a loaded cost of $590,000per year are used to manually weigh real rubber, synthetic rubber, carbon black, oils, and other components prior to manual insertion in a Banbary mixer that provides a homogeneous blend of rubber for making tires (rubber products). New technology is available that has the reliability and consistency desired to equal or exceed the quality of blend now achieved manually. It requires an investment of $2,250,000, with $93,000 per year operational costs and will replace all the manual effort described above. The planning horizon is 8 years, and there will be a $275,000 salvage value at that time for the new technology. Marginal taxes are 25%, and the after-tax MARR is 10%.

- A4-5 A production facility is currently utilizing carbon steel tubing. The current process will require the injection of chemicals to control tubing corrosion due to high temperatures, pressures, and corrosive chlorides in the transported product. It is proposed to replace the car- bon steel that cost $12 per foot with an installation cost of $125,000 last year, with a chrome stainless steel tubing that would cost $68 per foot today (time zero). 20,000 feet of tubing would be required and installation costs are estimated to total $500,000 (also at time zero). Annual cost savings in chemicals, labor, and chemical injection equip- ment are projected to be $550,000 in year one. The year one savings would escalate at an annually compounded rate of 7% per year beginning in year 2. For simplicity, use a 6-year evaluation life with a salvage value of zero at the end of year 6.

- A client has an existing CAD/CAM system that costs $95,000 per year to lease (payable at the end of each year of use) and a new contract the client is considering entering will fix the price for over the next four years. The client is also considering purchasing a CAD/CAM system to replace its currently leased system (rather than renewing / entering a new lease contract). The new system will cost $450,000 to purchase and install. The system has an estimated life of five years, when it is expected to become obsolete, but it will have a salvage value of $25,000. The interest rate is projected to be 6% per year during the life of the project. a.
