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
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.
You need to determine whether a project is profitable or not in a long run. Based on the data given, which of theseprojects will be profitable according to engineering economy methods?a. θ = 3 yrs., Net Value: 0b. Accumulated (without interest) net values of the revenues, expenses and investments after 5 years is +300.c. Accumulated (without interest) net values of the revenues, expenses and investments after 4 years is +100.d. θ = 6 yrs., Net Value: +400
1. The Present Worth Method A project your firm is considering for implementation has these estimated costs and revenues: an investment cost of $50,000; maintenance costs that start at $5,000 at the end of year (EOY) 1 and increase by $1,000 for each of the next 4 years, and then remain constant for the following 5 years; savings of $20,000 per year (EOY 1–10); and finally a resale value of $35,000 at the EOY 10. If the project has a 10-year life and the firm’s MARR is 10% per year, what is the present worth of the project? Is it a sound investment opportunity?
4) Which of the following power plants is better investment, assuming 8% interest on the sinking fund and no salvage value in either case, taxes/insurance at 10% and interest on capital at 12%. Use ROR and Present Worth Method. - Coal plant which costs P1M, last 10 years and cost annually P100k to operate. - Fuel-oil plant which costs P800k will last 7 years and cost annually P70k to operate.
A project is being considered that has a first cost of $12,500, creates $5000 in annual cost savings, requires $3000 in annual operating costs, and has a salvage value of $2000 after a project life of 3 years. If interest is 10% per year, which formula calculates the project’s present worth? (a) PW = 12,500(P/F, 10%, 1) + (− 5000 + 3000) (P/A, 10%, 3) − 2000(F/P, 10%, 3) (b) PW = − 12,500 + (5000 − 3000) (P/A, 10%, 3 ) − 2000(P/F, 10%, 3) (c) PW = 12,500(F/P, 10%, 3) + (5000 − 3000) (F/A, 10%, 3) + 2000 (d) PW = − 12, 500 + 5000(P/A, 10%, 3) − 3000 (P/A, 10%, 3) + 2000(P/F, 10%, 3)
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%
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…
An iron ore of 50x10^6 ton was produced during 15 years and has been sold for $100 per ton Estimate the required investment if 0.4 turnover ratio was considered. If produced ton costs $28, what would be the net present value of the project when 8% safe rate and 15% rate of return assuming that the Investment will be depreciated within 15 years?

Engineering Economy Show the all Cash Flow Diagram. Don't use Excel You bought a new car which you intend to use as a public utility vehicle for P950,000. The expected life of the car is ten (10) years for its intended use. Your driver and you agreed that for the first five (5) years , your “boundary” is P1,500.00 per day and P1,000.00 per day for the rest of its economic life. You also expected a repair and maintenance costs of P30,000 every six (6) months from year one (1) to five (5) and P50,000 from year six (6) to ten (10). At the end of 10 years you can sell the car for P100,000. If your MARR on invested capital is 15% every (6) months, determine whether this is a good investment. Use the Annual Worth , Present Worth , or the Future Worth method in your solution. Indicate all other assumptions you use in your analysis.
