A five-year project has an initial fixed asset investment of $613,600, an initial net working capital investment of $22,200. The project will have an annual operating cash flow (OCF) of (-$76,540). The fixed asset is fully depreciated over the life of the project and has no salvage value. The net working capital will be recovered when the project ends. The required return is 11.7 percent. What is the project's equivalent annual cost, or EAC? O-$248,052.76 O-$182,309.18 O-$147,884.01 O $242,212.22
An investor is considering two mutually exclusive projects. She can obtain a 6% before tax rate of return on external investements but she requires a minimum attractive rate of return or 7% for these projects. Use a 10 year analysis period to compute the incremental rate of return from investing in Project A rather than Project B. Project A Project B initial $58500 $48500 net uniform annual income 6648 0 salvage value 10 yrs hence 30000 138000 computed rate of return 8% 11%
Problem Solving. Solve the following problems completely. 4. Atty. Gacayan invested P280, 000 which will be used in a project that will produce auniform annual revenue of P180,000 for 5 years and then have a salvage value of 16% ofthe investment. Out-of-pocket costs for operation and maintenance will be P80,000 peryear. Taxes and insurance will be 3% of the first cost per year. Atty Gacayan expectscapital to earn not less than 30% before income taxes. Determine if the investment is goodand Calculate the following:a. Calculate using Rate of Return Method.b. Payback period of the investment.
An untreated wooden pole that will last 10 years under a certain soil condition costs P 12,000. If a treated pole will last for 20 years, what is the maximum justifiable amount that can be paid for the treated pole? Assume 1% tax of the first cost for the treated pole and 12% interest rate. Use annual cost method.
Methods of Economy Studies An investment of P 250,000 can be made in a project that will produce a uniform annual revenue of P 192,800 for 5 years and then have a salvage value of 10% of the first cost. Operation and maintenance will be P 72,000 per year. Taxes and insurance will be 4% of the first cost per year. The company expects capital to earn 20% before income taxes. Show whether or not the investment is justified economically using1. Present Worth (PW) method2. Future Worth (FW) method3. Annual Worth (AW) method4. Rate of Return (ROR) method5.

1 Southwest Airlines (SWA) is planning to expand its fleet of jets to replace some old planes and to expand its routes. It has received a proposal from Boeing to purchase 112 737’s over the next 4 years. What annual net revenue must each jet produce to break even on its operating cost? The analysis should be done by finding the EUAC for the 10-year planned ownership period. SWA has a MARR of 12%, purchases the jet for $22 million, has operating and maintenance costs of $3.2 million the first year, increasing 8% per year, and performs a major maintenance upgrade costing $4.5M at end of Year 5. Assume the plane has a salvage value at end of Year 10 of $13 million.
3. The annual worth method An office supply company has purchased a light duty delivery truck for $15,000. It is anticipated that the purchase of the truck will increase the company’s revenue by $10,000 annually, whereas the associated operating expenses are expected to be $3,000 per year. The truck’s market value is expected to decrease by $2,500 each year it is in service. If the company plans to keep the truck for only 2 years, what is the annual worth of this investment? The MARR = 18% per year
4. A government is planning to implement a new traffic control and surveillance system. The maintenance cost of the system is $1,200,000 per year. It is believed that the new system can help 3,000 driver saving 8 hours per year. The average wage of the people in this country is $150 per hour. It is expected that the system can be used for 5 years, i.e., the first benefit and cost are B1 and C1 respectively, while the last are B5 and C5. (a) What is the value of time saved by the new system per year? (b) Suppose the market interest rate is 5%. Calculate the net present value of this system. Should the system be launched? (c) Suggest two reasons to explain why the market interest rate in part (b) may be too high to evaluate the project. Should the system be launched if the interest rate is adjusted according to your suggestions?
E2 A steel bridge on Louisiana state highway near the Gulf of Mexico is costing $450.000 yearlyin maintenance large chipping, priming, and painting. It originaly cost $1.600.000 when it wasbuilt 15 years ago. The Louisiana bridge engineers estimate that its remaining life is 10 years,then it will need to be replaced because of increased traffic. Its salvage value at any point intime is zero, because the cost of demolition will most like equal its value as scrap steel.A concrete bridge is considered to be the best challenger. It will cost $3.000.000 to build and$100.000 annually in maintenance costs. Its estimated life is 50 years. Its resale value may becounted as zero at any time during its life.No taxes of any kind will be considered for this government project. All costs are in constantdollars of year 0. Inflation may be ignored. Assume that annual benefits for either structure areexactly the same. A discount rate of 10 percent is to be used in analysis.(a) What is the economic life…
8- The life of a project is 10 years. An equipment is needed for this project. Two alternatives are available. Equipment A has an initial cost of $5000.00, an annual maintenance cost of $300.00, and a salvage value of $800.00 after 5 years. Equipment B has an initial cost of $7000.00, an annual maintenance cost of $400.00, lasts for 10 years and has no salvage value. If the interest rate is 6%: a) Equipment A should be purchased. b) Equipment B should be purchased. c) No equipment should be purchased. d) There is no difference in choosing between A or B.
14.28 A new toll bridge is to be constructed over the Green River at a cost of $120M. The bridge requires maintenance costing $4000 annually over its 50-year life. Every 10 years, the bridge will require repainting at a cost of $1M. The value to motorists using this bridge is estimated to be $1.60 per trip. If the interest rate is 10% and 25,000 vehicles per day travel over the bridge, how much toll should be charged for each crossing? Rounding that toll up to the nearest nickel, what is the consumers’ surplus? 14.29 A dam may be built at a cost of $10M to elimi- nate the periodic flooding that Lowville experi- ences. That flooding averages a cost of $300K per year. Additional expenses can be incurred to divert water to another area for irrigation, to add electric power generation, and to permit recre- ation. Which alternative is best? Since political support is crucial, allocate the costs to the uses. The…
3. One of four ovens at the bakery is being considered for replacement. Its salvage value and maintenance costs are given in the table below for several years. A new oven costs P80,000 and this price includes a complete guarantee of the maintenance costs for the first two years, and it covers a good proportion of the maintenance costs for 3 years and 4 years. The salvage value and maintenance costs are summarized in the table below. Both the old and new ovens have similar productivities and energy costs. Should the oven be replaced this year if the MARR equals to 10%?
