The state is considering three proposals for increasing the capacity of the main drainage canal in an agricultural region. Proposal A requires dredging the canal. The state is planning to purchase the dredging equipment and accessories for $650,000. The equipment is expected to have a 10-year life with a $17,000 salvage value. The annual operating costs are estimated to total $50,000. To control weeds in the canal itself and along the banks, environmentally safe herbicides will be sprayed during the irrigation season. The yearly cost of the weed control program is expected to be $120,000.
Proposal B is to line the canal walls with concrete at an initial cost of $4 million. The lining is assumed to be permanent, but minor maintenance will
be required every year at a cost of $5000. In addition, lining repairs will have to be made every 5 years at a cost of $30,000.
Proposal C is to construct a new pipeline along a different route. Estimates
are: an initial cost of $6 million, annual maintenance of $3000 for right-of-way, and a life of 50 years.
Compare the alternatives on the basis of annual worth, using an interest rate of 5% per year.

- Alfred Home Construction is considering the purchase of five dumpsters and the transport truck to store and transfer construction debris from building sites. The entire rig is estimated to have an initial cost of $125,000, a life of 8 years, a $5000 salvage value, an operating cost of $40 per day, and an annual maintenance cost of $2000. Alternatively, Alfred can obtain the same services from the city as needed at each construction site for an initial delivery cost of $125 per dumpster per site and a daily charge of $20 per day per dumpster. An estimated 45 construction sites will need debris storage throughout the average year. If the minimum attractive rate of return is 12% per year, how many days per year must the equipment be required to justify its purchase?arrow_forwardCity Towing is considering the purchase of a new tow truck. The garage currently has no tow truck, and the $100,000 price tag for a new truck would be a major expenditure. The expected useful life is 7 years. The owner of the garage has compiled the following estimates in trying to determine whether the tow truck should be purchased: Purchase of truck $100,000 Salvage value $15,000 Additional net inflows per year $16,000 Repairs required at the end of year 3 $5,000 Minimum required return on investments 12%arrow_forwardA remotely located air sampling station can be powered by solar cells or by running an above ground electric line to the site and using conventional power. Solar cells will cost $17,400 to install and will have a useful life of 5 years with no salvage value. Annual costs for inspection, cleaning, and other maintenance issues are expected to be $2,100. A new power line will cost $26,000 to install, with power costs expected to be $1,000 per year. Since the air sampling project will end in 5 years, the salvage value of the line is considered to be zero. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.At an interest rate of 10% per year and using an AW analysis, which alternative should be selected? The annual worth of installing solar cells is $− , and the annual worth of installing a new power line is $− . The alternative to be selected is .arrow_forward
- An electric utility is considering a new power plant in northern Arizona. Power from the plant would be sold in the Phoenix area, where it is badly needed. Because the firm has received a permit, the plant would be legal; but it would cause some air pollution. The company could spend an additional $40 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. The plant without mitigation would require an initial outlay of $269.87 million, and the expected cash inflows would be $90 million per year for 5 years. If the firm does invest in mitigation, the annual inflows would be $93.62 million. Unemployment in the area where the plant would be built is high, and the plant would provide about 350 good jobs. The risk adjusted WACC is 16%. Calculate the NPV and IRR with mitigation. Enter your answer for NPV in millions. For example, an answer of $10,550,000 should be entered as 10.55.

The project falls under the government’s subsidy program for encouraging local agricultural products and is eligible for a one-time rebate of 25% on any initial equipment installed for the project. The initial equipment (IE) will cost $41,000,000. At the end of year 1, an additional equipment (AE) costing $2,500,000 will be needed at the end of year 3. At the end of seven (7) years, the original equipment, IE, will have no resale value but the supplementary equipment, AE, can be sold for $50,000. A working capital of $1,350,000 will be needed. The project is forecast to generate sales of agri-products over the seven years as follows:Year 1 70,000 unitsYear 2 100,000 unitsYears 3-5 250,000 unitsYears 6-7 325,000 units A sale price of $150 per unit for the first two years is expected and then decline to $90 per unit thereafter as the newness of the product loses some sheen.

- Two firms, A and B, each currently dump 50 tonnes of chemicals into the local river. The government has decided to reduce the pollution and from now on will require a pollution permit for each tonne of pollution dumped into the river. The government will sell 40 pollution permits for $75 each. It costs Firm A $100 for each tonne of pollution that it eliminates before it reaches the river, and it costs Firm B $50 for each tonne of pollution that it eliminates before it reaches the river. Between the cost of permits and the cost of eliminating pollution, the likely outcome is Firm A spends and Firm B spends cross out $4000; $3500 cross out O b. $3000; $2500 cross out O c. $3000; $3500 cross out O d. $4000; $2500 cross out O e. $5000; $2500 cross out O f. $5000; $3500arrow_forwardA steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $25,000 and would make the overpass adequate for an additional 6 years of service. If the overpass is torn down now, the scrap value of the steel would exceed the removal cost by $15,000. If it is reinforced, it is estimated that its net salvage (market) value would be $18,000 at the time it is retired from service. A new pre- stressed concrete overpass would cost $140,000 and would meet the foreseeable requirements of the next 40 years. Such a design would have no scrap value or market value. It is estimated that the annual expenses of the reinforce overpass would exceed those of the concrete overpass by $3,200.
