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 invest in a piece of equipment costing $30,000. The equipment will be used for two years, at the end of which time the salvage value of the machine is expected to be $10,000. The machine will be used for 5,000 hours during the first year and 8,000 hours during the second year. The expected annual net savings in operating costs will be $25,000 during the first year and $40,000 during the second year. If your interest rate is 10%, what would be the equivalent net savings per machine-hour?

A small manufacturing firm is considering the purchase of a new machine to modernize one of its current production lines. Two types of machines are available on the market. The lives of Machine A and Machine B are four years and six years, respectively, but the firm does not expect to need the service of either machine for more than five years. The machines have the following expected receipts and disbursements: After four years of use, the salvage value for Machine B will be $1,000. The firm always has another option: to lease a machine at $3,000 per year, fully maintained by the leasing company. The lease payment will be made at the beginning of each year.(a) How many decision alternatives are there?(b) Which decision appears to be the best at i = 10%?

- 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.)arrow_forwardJake’s Shipping, Inc. needs to purchase a new fleet of light trucks for its shipping business. The firm is trying to decide whether to purchase trucks with diesel engines or trucks with gasoline engines. The diesel truck will have a useful life of 12 years, after which it will need to be replaced. The diesel truck costs $110,000 to purchase and its annual maintenance and operation costs will depend on the cost of regular maintenance/repairs and the cost of diesel fuel. In Years 1 through 5, its annual maintenance/repair costs are expected to be $2000 per year. In Years 6 through 12, its annual maintenance/repair costs are expected to be $2500 per year. The firm expects that the diesel truck will use 5,900 gallons of diesel fuel per year (Years 1 through 12) and believes that diesel fuel will cost $2.65 per gallon, on average, during the life of the truck. The gasoline truck only costs $60,000 to purchase but will have a useful life of only 4 years, after which it will need to be…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?

- 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_forwardConsider the following two mutually exclusive service projects with projectlives of three years and two years, respectively.

It is about to launch a new product, the 'Energy Buster', a unique air conditioning unit which is capable of providing unprecedented levels of air conditioning using a minimal amount of electricity. The technology used in the Energy Buster is unique so Ahlia Co has patented it so that no competitors can enter the market for two years. The company's development costs have been high and it is expected that the product will only have a five-year life cycle. Ahlia Co is now trying to ascertain the best pricing policy that they should adopt for the Energy Buster's launch onto the market. Demand is very responsive to price changes and research has established that for every $15 increase in price, demand would be expected to fall by 1,000 units.

Two installations are being considered to provide for water storage in a chemical plant. A tank on a tower or a tank of equal capacity placed on a hill some distance from the plant. The cost of installing the tank and tower is estimated at P350,000. The cost of installing the tank on the hill, including the extra length of service lines, is estimated at P300,000. The hill installation will require an additional investment of P30,000 in pumping equipment whose life is estimated to be 15 years with a salvage value of P2,500. The life of the two installations is estimated to be 30 years. Annual cost of labor, electricity, and maintenance incident to the pumping equipment is estimated at P3,000. Taxes and insurance for both are 2.5% of the first cost. Money is worth 18% effective.Which alternative should be used? Write a brief interpretation of your answers. (USE PW and EUAC)arrow_forward
