A new highway is to be constructed. Design A calls for a concrete pavement costing $80 per foot with a 16-year life; three paved ditches costing $4 per foot each; and two box culverts every mile, each costing $9,000 and having a 16-year life. Annual maintenance will cost $1.600 per mile; the culverts must be cleaned every four years at a cost of $400 each per mile. Design B calls for a bituminous pavement costing $30 per foot with a 8-year life; two sodded ditches costing $1.55 per foot each; and three pipe culverts every mile, each costing $2,200 and having a 8-year life. The replacement culverts will cost $2,400 each. Annual maintenance wil cost $2,600 per mile; the culverts must be cleaned yearly at a cost of $225 each per mile; and the annual ditch maintenance will cost $1.65 per foot per ditch. Compare the two designs on the basis of equivalent worth per mile for a 16-year period. Find the most economical design on the basis of AW and PW if the MARR is 12% per year.

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? $

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%.

Problem 1: Loblolly Pine Plantation (Known Rotation Range) A forester is considering planting loblolly pine on a recently acquired site. They expect the optimal rotation to be between 20 and 40 years. The following information is available: • • • • Land cost: $500/acre (one-time cost at year 0) Establishment cost: $250/acre at year 0 Annual property taxes: $3/acre/year Timber price: $100/acre/year (assumed constant throughout the rotation) Discount rate: 7% Calculate the LEV for each year between 20 and 40 years and identify the optimal rotation age that maximizes LEV.
A firm is considering the “make vs. buy” question for a subcomponent. If the part is made in-house, the production data would be: first cost = $350, 000; annual costs for operation = $45, 000; salvage value = $15, 000; project life = 5 years; interest = 10%; and material cost per unit = $8.50. If annual production is 10,000 units, the maximum amount that the firm should be willing to pay to an outside vendor for the subcomponent is nearest? (a) $10 per unit (b) $16 per unit (c) $22 per unit (d) $28 per unit?

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…
