Advanced Electrical Insulator Company is considering replacing a brokeninspection machine, which has been used to test the mechanical strength of electrical insulators with a newer and more efficient one. If repaired, the old machine can be used for another five years although the firm does not expect to realize any salvage value from scrapping it in five years. Alternatively, the firm can sell the machine to another firm in the industry now for $5,000. If the machine is kept, it will require an immediate $1,200 overhaul to restore it to operable condition. The overhaul will neither extend the service life originally estimated nor increase the value of the inspection machine. The operating costs are estimated at $2,000 during the first year and are expected to increase by $1,500 per year thereafter. Future market values are expected to decline by $1,000 per year. The new machine costs $10,000 and will have operating costs of $2,000 in the first year, increasing by $800 per year…
You are evaluating two different silicon wafer milling machines. The Techron I costs $228,000, has a three-year life, and has pretax operating costs of $59,000 per year. The Techron II costs $400,000, has a five-year life, and has pretax operating costs of $32,000 per year. For both milling machines, use straight-line depreciation to zero over the project’s life and assume a salvage value of $36,000. If your tax rate is 24 percent and your discount rate is 8 percent, compute the EAC for both machines.
Note: Your answer should be a negative value and indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.
Two 150-horsepower (HP) motors are being considered for installation at amunicipal sewage treatment plant. The first costs $4,500 and has an operating efficiency of 83%. The second costs $3,600 and has an operating efficiency of 80%. Both motors are projected to have zero salvage value after a life of 10 years. All the annual charges, such as insurance and maintenance, amount to a total of 15% of the original cost of each motor. If power cost is a flat 5 cents per kilowatt-hour, which alternative should be chosen at 5,000 operating hours per year? Assume an interest rate of 6%. (A conversion factor you might find useful is IHP = 746watts = .746kilowatts.)

- A company needs to acquire a machine to increase its production. To do so, you will need to make an initial investment of $150,000. Furthermore, the use of the machine will result in annual operating and maintenance costs of around 2,500.00, for a useful life of 10 years and a residual value of %30,000. At the end of 4 and 8 years, it requires revisions that cost $20,000 and $10,000 respectively. At the end of the fifth year, it must undergo a general renovation at the cost of .$45,000. Under these conditions, what is the Uniform Equivalent Annual Cost generated by the company's acquisition of the machine?

- New pumper system equipment is under consideration by a Gulf Coast chemical processing plant. One crucial pump moves highly corrosive liquids from specially lined tanks on intercoastal barges into storage and preliminary refining facilities dockside. Because of the variable quality of the raw chemical and the high pressures imposed on the pump chassis and impellers, a close log is maintained on the number of hours per year that the pump operates. Safety records and pump component deterioration are considered critical control points for this system. As currently planned, rebuild and M&O cost estimates are increased accordingly when cumulative operating time reaches the 6000-hour mark. Information: You are the safety engineer at the plant. Estimates made for this pump are as follows: First cost:$800,000 Rebuild cost: $150,000 whenever 6000 cumulative hours are logged. Each rework will cost 20% more than the previous one. A maximum of three rebuilds are allowed. M&O costs: $25,000…arrow_forwardIf a project costs $90,000 and is expected to return $24,500 annually, how long does it take to recover the initial investment?

The machine is expected to have a useful life of five years, after which the machine can be sold as scrap for an estimated £5000. The firm plans to issue bonds to pay for the machine and intends to treat the interest rate on the bonds as the relevant discount rate for evaluating the project. The machine will cost the firm £175,000, all of which must be paid at the beginning of the project. The new stamping machine will reduce costs £50,000 per year, for each year of the machineʹs life. The firm treats all the cost savings as if they occur at year end. Should the firm plan to undertake the investment project, bonds will be issued in approximately three months. The firm has estimated the supply and demand for loanable funds given by these equations:LD = 25,000,000 - 125,000,000r LS = 2,500,000 + 62,500,000r(1) Given the information above, should the firm undertake the investment in the…arrow_forward
- Chatham Automotive purchased new electric forklifts to move steel automobile parts two years ago. They cost $80,000 each, including the charging stand. In practice, it was found that they did not hold a charge as long as claimed by the manufacturer, so operating costs are very high. As a result, their current salvage value is about $10,000. Chatham is considering replacing them with propane models. New propane forklifts cost $59,000 each. After one year, they have a salvage value of $40,000 and thereafter decline in value at a declining-balance depreciation rate of 20 percent, as does the electric model from this time on. The MARR is 7 percent. Operating costs for the electric model will be $18,000 this year, rising by 12 percent per year. Operating costs for the propane model will initially be $12,000 over the first year, rising by 12 percent per year. Should Chatham Automotive replace the forklifts now?

The sprayer can be used for another 10 years and will have a zero salvage value at that time. The annual operating and maintenance costs for the sprayer amount to $15,000 per year. Due to an increase in business, a new sprayer must be purchased, either in addition to or as a replacement for the old sprayer. Option 1: if the old sprayer is retained, a new, smaller capacity sprayer will be purchased at a cost of $48,000; this new sprayer will have a $5,000 salvage value in 10 years and an annual operating and maintenance costs of $12,000. The old sprayer has a current market value of $6,000. Option 2: if the old sprayer is sold, a new sprayer of larger capacity will be purchased for $84,000. This sprayer will have a $9,000 salvage value in 10 years and annual operating and maintenance costs of $24,000.

Construction involves a cash outlay of $265,000 at the end of each of the next two years. At the end of the third year, the company will receive payment of $625,000. The company can speed up construction by working an extra shift.
