A large stale university. currently facing a severe parking shortage on its campus, is considering constructing parking decks off-campus. A scheduled service composed of minibusses could pick up students at the off-campus parking deck and quickly transport them to various locations on campus. The university would charge a small fee for each shuttle ride, and the students could be quickly and economically transported to their classes. The funds raised by the shuttle would be used to pay for minibusses, which cost about $150,000 each. Each minibus has a 12-year service life with an estimated salvage value of $3.000. To operate each minibus. The following additional expenses must be considered:
Item Annual Expense
Driver $40,000
Maintenance $7,000
Insurance $2000
If students pay 10 cents for each ride, determine the annual ridership (i.e., the number of shuttle rides per year)…
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:
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.)

One alternative is to spend $10 million to increase the size of an existing reservoir in an environmentally acceptable way. Added annual upkeep will be $25,000 for this option. A second option is to drill new wells and provide added pipelines for transportation to treatment facilities at an initial cost of $1.5 million and annual cost of $120,000. The reservoir is expected to last indefinitely, but the productive well life is only 10 years. Compare the alternatives at 5% per year.arrow_forward
- A County Highway Department is considering either replacing or rehabilitating a bridge which crosses over a river dividing two nearby communities. Rehabilitation can be done either by force account for by contract. The cash flows associated with replacement and rehabilitation options for this bridge are shown in Table 1. Determine the most cost- effective option. Assume that interest is annually compounded at 6%. After the service life of the rehabilitated bridge is completed, the bridge will be replaced with the same cash flow as the present replacement option. Solve the problems using the annual cost method. Assume replacement in perpetuity. Cash Flows Associated with Replacement and Rehabilitation Option I: Replacement (Service life of the new bridge is 40 years) Capital Investment Initial = 45,000 15th year = 8,000 20th year = 1,500 30th year = 6,000 Annual maintenance cost = $500/year (throughout the service life) Salvage of existing bridge beams = $1,000 Option 2:…arrow_forwardThe City of Manila contemplates to increase the capacity of its existing water transmission line. Two plans are under consideration. Plan A requires the construction of a parallel pipe line, the flow being maintained by gravity. The initial cost is P2,750,000 and the life is 40 years, with an annual operating cost of P50,000. Plan B requires the construction of a booster pumping station costing P1,050,000 with a life of 40 years. The pumping equipment costs an additional amount of P250,000. It has a life of 20 years and a salvage value of P25,000. The annual operating cost is P165,000. If the interest rate is 12%, which is the more economical plan and by how much lower than the other?

- An electrical utility is experiencing sharp power demand, which continues to grow at a high rate in a certain local area. Two alternatives to address this situation are under consideration. Each alternative is designed to provide enough capacity during the next 25 years. Both alternatives will consume the same amounts of fuel, so fuel cost is not considered in the analysis. The alternatives are detailed as follows:Alternative A: Increase the generating capacity now so that the ultimatedemand can be met with additional expenditures later. An initial investment of $30 million would be required, and it is estimated that this plant facility would be in service for 25 years and have a salvage value of $0.85 million. The annual operating and maintenance costs (including income taxes) would be $0.4 million.Alternative B: Spend $10 million now, and follow this expenditure withadditions during the 10th year and the 15th year. These additions wouldcost $18 million and $12 million. respectively.…arrow_forwardSacramento is considering building a temporary bridge to cut travel time during the three years it will take to build the new permanent “I” Street bridge to West Sacramento.
