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%? Item Initial cost Service life Estimated salvage value Annual O&M costs Cost to change oil filter every other year Engine overhaul Machine A Machine B $8,500 $6,500 4 years 6 years $600 $1,000 $800 $520 $100 None $200 (every 3 years) $280 (every 4 years)

Alpha software is considering replacing one of their computer servers with a newer model, the curent model in question is now worth $1,200,000 (fiuture market values is forecasted to drop by 20% per year). If kept the current server system will require an immediate overhaul that costs $200,000. The operation cost of this server is $170,000 for the first year and will increase by 33% afterwards.A new server model is available which has a 10 years of service life, costs $2,500,000 with O&M costs of$120,000 for the 1st year which increases by 32% for subsequent years. The new server's (challenger's)market value will drop 25% per year through its service life.Knowing that the company's MARR is 10%A] Plot total AE cost (uniform annual equivalent cost) vs useful life for the defender as well as thechallenger up to 10 years.B] Find the economic lives of the defender & the challenger.C Determine if when the defender should be replaced within 10 years.
Lang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $252,000, has a four-year life, and requires $78,000 in pretax annual operating costs. System B costs $354,000, has a six-year life, and requires $72,000 in pretax annual operating costs. Suppose LISC always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is 34 percent and the discount rate is 8 percent. Calculate the EAC for both conveyor belt systems. (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) System A System B EAC 127564.C Which conveyor belt system should the firm choose? • System B ○ System A
The gaming commission is introducing a new lottery game called Infinite Progresso. The winner of the Infinite Progresso jackpot will receive $900 at the end of January, $1,800 at the end of February, $2,700 at the end of March, and so on up to $10,800 at the end of December. At the beginning of the next year, the sequence repeats starting at $900 in January and ending at $10,800 in December. This annual sequence of payments repeats indefinitely. If the gaming commission expects to sell a minimum of 1,200,000 tickets, what is the minimum price they can charge for the tickets to break even, assuming the commission earns 9.00 % / year on its investments and there is exactly one winning ticket? $ Do all calculations to 5 decimal places and round final answer to 2 decimal places. Tolerance is +$0.03.
You bought a new car which you intend to use as a public utility vehicle for P950,000. The expected life of the car is ten (10) years for its intended use. Your driver and you agreed that for the first five (5) years , your “boundary” is P1,500.00 per day and P1,000.00 per day for the rest of its economic life. You also expected a repair and maintenance costs of P30,000 every six (6) months from year one (1) to five (5) and P50,000 from year six (6) to ten (10). At the end of 10 years you can sell the car for P100,000. If your MARR on invested capital is 15% every (6) months, determine whether this is a good investment. Use the Future Worth method in your solution. Indicate all other assumptions you use in your analysis.Use manually solve and don't use excel.
Consider a proposal to enhance production of tortillas en a taqueria. The new machine is estimated to cost $20 million and will incur an additional $1 million per year in maintenance costs. The machine will produce annual savings of $7 million each year. The Minimum acceptable rate of return (MARR) is 10% per year, and the study period is five years at which time the machine will be obsolete (worthless). What is the maximum (minimum) percentage of maintenance cost can change that reverse your decision? (write upto 4 decimals.)
A manufacturing engineer is considering whether to repair or replace a broken machine. The first alternative (Alternative “A”) is to repair the machine with an initial cost of $15,000, an annual maintenance of $700 per year, with no salvage value at the end of its five-year useful life. The second alternative (Alternative “B”) is to replace the machine for $30,000. The maintenance cost starts in the second year at $200 and increases $200 per year in all subsequent years. There is an anticipated salvage value of $5,000 at the end of 20 years. Assuming interest rate is 6% and an analysis period of 20 years, what would be the preferable alternative ?
A wastewater treatment facility is planning to purchase a new sludge dryer equipment to replace its present unit. The new sludge dryer would cost P135,402 with a five (5) year-life, and no estimated salvage value. Its operating cost would be P150,064 a year. The sludge dryer that they are currently using at present has a book value of P75,260 and a remaining life of 5 years. It has also no estimated salvage value. And its variable operating cost would be cost P187.568 a year. Money is worth 10%. Using ROR method, which is profitable, to buy the new sludge dryer or retain the old equipment?

The capitalized cost of a new printing equipment was found to be P426,000.00.The rate of interest was 12%, with a salvage value of P30,000.00 t the end of a service life of 8 years. Assuming that the cost of perpetual replacement remains constant, determine the original cost of the equipment.
A new office building has been constructed at a cost of $3.000,000, It is estimated to have a life of 50 years with a value at that time of $200.000, It will have maintenance costs of $10,000 per year. It will also have major repairs costing $80,000 that occur at years 10, 20, 30 and 40. It will have additional repairs at the end of year 25 costing $250,000. Determine the equivalent uniform annual cost if the rate of interest of the firm is 7%.

Two machines are being considered to replace an old one. Machine 1 costs $80,000 and Machine 2 costs $120,000. Based on the capacity of these machines, it can be safely estimated that the revenue of Machine 1 will be $30,000 for year 1 and $41,500 for Machine 2. It is also assumed that the capacity could be increased and thereby the revenue by 20% every year for the next few years. The maintenance costs for both machines will be $2,000 and the amount will increase by $5,000 every year for the next few years. According to other companies that use similar machines, these machines are capable of producing products for 5 years before major breakdowns occur. Since this is a rough estimate, you can use straight-line depreciation over the next five years. The marginal tax rate for this company is 40%. a) Assuming an after-tax MARR of 15%, calculate the PW of the after-tax cash flow. b) Perform a sensitivity analysis by changing the after-tax MARR from 10% to 20%.
