A large standby electricity generator in a hospital operating room has a first cost of $74,750 and may be used for a maximum of 6 years. Its salvage value, which decreases by 15% per year, is described by the equation S-74,7501-0.15), where n is the number of years after purchase. The operating cost of the generator will be constant at $8,000 per year, and the interest rate is 12% per year. Determine the economic service life and associated AW values. The economic service life is years and the AW value is $-1

To maintain its newly acquired equipment, the company needs P40,000 peryear for the first five years. And P60,000 per year for the next five years. Inaddition, an amount of P140,000 would also be needed at the end of the fifthand eight years. At 6%, what is the present worth of these costs?
Ramsis is a beavy equipment rental company. It is considering the purchase of Tower crane at a price of BD 775,000. This crane is expected to operate for 12 years before retirement with no salvage value at the end. The company is planning to rent the crane for BD 108,000 per year starting year 2 and the rental increases by 10% thereafter Cost of this maintenance is expected to be BD 15,000 each year a ) What is the discounted payback period, if the MARR 8 % per year? b ) In your engineering analysis study, which method would you select ( Payback or Present worth) to solve this problem? And why?
A small strip-mining coal company is trying to decide whether it should purchase or lease a new clamshell. If purchased, the “shell” will cost $140,000 and is expected to have a $45,000 salvage value after 6 years. Alternatively, the company can lease a clamshell for only $14,000 per year, but the lease payment will have to be made at the beginning of each year. If the clamshell is purchased, it will be leased to other strip-mining companies whenever possible, an activity that is expected to yield revenues of $10,000 per year. If the company’s MARR is 12% per year, should the clamshell be purchased or leased on the basis of a future worth analysis? Assume the annual M&O cost is the same for both options. The future worth when purchased is $ . The future worth when leased is $ .
$100,000 is invested in equipment having a negligible salvage value regardless of when the equipment is replaced. O&M costs equal $25,000 the first year and increase $5,000 per year. Based on a MARR of 10%, what are the optimum replacement interval and minimum EUAC?
A bridge is to be constructed now as part of a new road. Engineers have determined that traffic density on the new road will justify a two-lane road and a bridge at the present time. Because of uncertainty regarding future use of the road, the time at which an extra two lanes will be required is currently being studied. The two-lane bridge will cost $220,000 and the four-lane bridge, if built initially, will cost $420,000. The future cost of widening a two-lane bridge to four lanes will be an extra $220,000 plus $26,000 for every year that widening is delayed. The MARR used by the highway department is 18% per year. The following estimates have been made of the times at which the four-lane bridge will be required:
The initial cost of a pickup truck is $12,748 and will have a salvage value of $4,360 after five years. Maintenance is estimated to be a uniform gradient amount of $121 per year, with zero dollar for first year maintenance. The operation cost is estimated to be $0.3 per mile for 351 miles per month. If the interest rate is 12%, what is the annual equivalent cost (AEC) for the truck?
Question 8 Canada's Wonderland has decided to carry out an analysis to determine when one of its roller coasters should be replaced. The existing roller coaster was purchased 25 years ago for $715,000. The costs of operating and maintaining this ride for a 5-year study period are predicted to be $70,000 in year 1 and would increase by $1,300 each year thereafter (i.e. $71,300 in year 2, $72,600 in year 3, etc.) Canada's Wonderland uses a MARR of 10% for roller coaster projects. (a) If the roller coaster loses value at a rate of 7% per year, what is the salvage value at the end of the study period? (b) What is the EAC for operating & maintenance costs (O&M) after 4 years in the study period? (c) Supposing the salvage value after 2 years in the study period is $100,773, what is the EAC for capital costs after 2 years in the study period? . (d) What is the economic remaining life of the roller coaster (i.e. in the study period)?
The city of Oak Ridge is considering the construction of a four kilometer (km) greenway walking trail. It will cost $1,000 per km to build the trail and $300 per km per year to maintain it over its 20-year life. If the city’s MARR is 7% per year, what is the equivalent uniform annual cost of this project? Assume the trail has no residual value at the end of 20 years.
Matchim's Paving is investing in a new wider paving machine that will cost $131000, which is expected to return $22500 per year of the next 12 years. At the end of the 12 years the paving machine is expected to have a salvage value of $20000. Assuming the cash flow is at the end of the year, what is the Pay Back Period, in years, for the project?
Calculate the present worth of all costs for a newly acquired drill machine with an initial cost of P29,000,no trade-in value, a life of 10 years, and an annual operating cost of P13,000 for the first 4 years, increasing by 10% per year thereafter. Use an interest rate of 10% per year.
A construction firm is considering purchasing equipment that will reduce cost by P40,000. The equipment costs P300,000 and has a salvage value of P50,000 and a life of 7 years. The annual maintenance cost is P6,000. While not used by the firm, the equipment can be rented to others to generate an income of P10,000 per year. If the money can be invested for 8% return, is the firm justified in buying the equipment? (USE ROR Method) a. None of the choices b .I do not care c. No d. Yes
A firm has production capacity of 500 refrigerators per month and its fixed costs are P2,750,000 a month. The variable cost per unit is P11,500 and each unit can be sold for P20,000. Economic measures are instituted to reduce the fixed costs by 10% and the variable costs by 15%. Determine the old and new profits at 100% capacity. Determine the old and new breakeven points.
