Ch 5 economics Nancy’s Notions pays a delivery firm to distribute its products in the metro area. Delivery costs are $31,500 per year. Nancy can buy a used truck for $8,000 that will be adequate for the next 3 years. Operating and maintenance costs are estimated to be $24,000 per year. At the end of 3 years, the used truck will have an estimated salvage value of $3,200. Nancy’s MARR is 25%/year. What is the present worth of this investment? $
1. Breakeven Analysis An aerodynamic three-wheeled automobile (the Dart) runs on compressed naturalgas stored in two cylinders in the rear of the vehicle. The $13,000 Dart can cruise at speeds up to 80 miles per hour, and it can travel 100 miles per gallon of fuel. Another two-seater automobile costs $10,000 and averages 50 miles per gallon of compressed natural gas. If fuel costs $8.00 per gallon and MARR is 10% and 15%per year, over what range of annual miles driven is the Dart more economical? Assume a useful life of five years for both cars.2. Sensitivity Analysis We know the standard means of cutting the high cost of driving our automobiles—slow down your speed, no jack rabbit starts, inflate tires properly, clean air filters regularly, and so on. Another way to reduce the cost of driving is to join every bigrigger in the United States and half of Europe-go diesel. Diesels are inherently more efficient than gasoline engines because they deliver a third better fuel mileage. They…
A dam is proposed on a stretch of wild river, a river that is currently used for recreation. The dam will generate electricity. The dam will have a useful life of 50 years, after which its reservoir will be full of sediment and the dam will need to be removed. The following are characteristics of the dam: Initial Cost: $100,000,000 Electricity produced: 100,000 MWh per year, at $100/MWh. Cost of decommissioning dam: $10,000,000. Value of recreation lost: $5,000,000 per year. 1. If the social discount rate is 3% per year, is the dam a good idea? 2. If the social discount rate is 10% per year, is the dam a good idea? 3. Calculate the "cutoff" discount rate, c3 such that the dam is a good idea for discount rates c.
1. A replacement electric motor is being considered for purchased. It is capable of providing 200 hp. The pertinent data are follows: Cost - 3200 dollars Maintenance Cost per year - 50 dollars Life expectancy - 14years Salvage value - 1,452 dollars The motor is used for 400 h/year and the cost of electricity is 0.0 dollars/kWh. What is most nearly the effective annual cost using an interest rate of 10%
Calculate the annual net benefit from the given project summary. Capital Costs = $43,000; Revenue = $16,000/year; Operation and Maintenance Costs = $7,800/year Salvage Value = $19,000; Project Lifetime = 6 years; Effective Interest Rate = 0.09.
A new highway is to be constructed, and asphalt paving will be used. The asphalt will cost $150 per foot, including the material and the paving operation. Due to the heavy usage expected, the asphalt is expected to last 5 years before requiring resurfacing. It is anticipated that the cost of resurfacing will remain the same per foot. Concrete drainage ditches will be installed to each side of the highway; they will each cost $7.75 per foot to install. Ditches will have to be replaced every 15 years; the cost of replacing them will also be $7.75 per foot. Four pipe culverts will be installed every mile; each culvert will cost $8,000 and will last 10 years; replacement culverts will cost $10,000 each, indefinately. Annual maintanance of the highway will cost $9,000 per mile. Cleaning each culvert will cost $1,250 per year. Cleaning and maintaining each ditch will cost $3.75 per foot per year. Determine the capitalized cost (CC) per mile of highway using a MARR of 5%.
1. The example in the previous chapter, National Homebuilders, Inc. evaluated cut-and-finish equipment from vendor A (6-year life) and vendor B (9-year life). The PW analysis used the LCM of 18 years. Consider only the vendor A option now. The cash diagram shows the cash flows for all three life cycles (first cost $-15,000; annual M&O costs $-3500; salvage value $1000). Demonstrate the equivalence at i= 15% of PW over three life cycles and AW over one cycle. In previous example, present worth for vendor A was calculated as PW = $-45,036. cost (A) income year net cash flow 0 -15000 0 -15000 1 -3500 0 -3500 2 -3500 0 -3500 3 -3500 0 -3500 4 -3500 0 -3500 5 -3500 0 -3500 6 -18500 1000 -17500 7 -3500 0 -3500 8 -3500 0 -3500 9 -3500 0 -3500 10 -3500 0 -3500 11 -3500 0 -3500 12 -18500 1000 -17500 13 -3500 0 -3500 14 -3500 0 -3500 15 -3500 0 -3500 16 -3500 0 -3500 17 -3500 0 -3500 18 -3500 1000 -2500 ($45,036.36) annual W ($7,349.32)
