Ronald McDonald decides to install a fuel storage system for his farm that will save him anestimated 6.5 cents/gallon on his fuel cost. He uses an estimated 20,000 gallons/year on his farm.Initial cost of the system is $10,000 and the annual maintenance the first year is $25 and increasesby $25 each year thereafter. After a period of 10 years the estimated salvage is $3,000. If moneyis worth 12%, is it a wise investment?
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?
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)
A corporation uses a type of motor truck which costs P 250,000, with life of 2 years and final salvage value P 40,000. If money is worth 4% and using the annual cost method, what should be the life, in years, of another type of truck for the same purpose whose that cost P 312,614 with final salvage value P 50,000? Select one: a. 2.5 b. 4 c. 3.5 d. 3
Hinson’s Homegrown Farms needs a new irrigation system. System one will cost $145,000, have annual maintenance costs of $10,000, and need an overhaul at the end of year six costing $30,000. System two will have first-year maintenance costs of $5000 with increases of $500 each year thereafter. System two would not require an overhaul. Both systems will have no salvage value after 12 years. If Hinson’s cost of capital is 4%, using annual worth analysis determine the maximum Hinson’s should be willing to pay for system two.
Mr Dela Cruz is going to buy a new machine for manufacturing its product: Machine A has a first cost of P50,000; annual maintenance P6,000; life 12 years and salvage value of P2,000.

Solve with complete solution and draw the cash flow diagram 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 $500 each year until year 10 ; savings of $20,000 per year (EOY 1–10); and finally a resale value of $35,000 at the EOY 10.

IRR = ___ % d) Is it a sound investment opportunity? YES or NO e) Determine the Discounted Payback? ____ 5 years Note: For equivalent worth, round off the final answer to whole number. For Rate of Return, round off to two decimal places (in percentage)
5-27image If produced by Method A, a product’s initial capital cost will be $100,000, its annual operating cost will be $20,000, and its salvage value after 3 years will be $20,000. With Method B there is a first cost of $150,000, an annual operating cost of $10,000, and a $50,000 salvage value after its 3-year life. Based on a present worth analysis at a 15% interest rate, which method should be used?

Use AWM If the number of parts is 10,000 units, which lathe will you recommend? Use ROR If the number of parts is 10,000 units, which lathe will you recommend? Use PWM If the number of parts is 10,000 units, which lathe will you recommend? Use EUAC
Engineering Economy Calculate the Present Worth. 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.
A project is being planned that has an initial investment at time 0, annual revenuesand expenses, and a salvage value at the end of the project lifespan (20 years). The financialvalues are summarized below:Initial investment amount at time 0 $150,000Estimated annual revenue $34,500 per yearEstimated annual expenses $8,700 per yearEstimated salvage value at end of lifespan $10,000Minimum attractive rate of return (MARR) 15%a. Calculate the capital recovery amount CR(i%).b. Using the annual worth (AW) method, determine whether purchasing the equipmentis economically justified.c. Repeat part (a) using the internal rate of return (IRR) method based on annual worth(AW).d. Using the present worth (PW) method, determine the break-even time period afterwhich purchase of the equipment generates a profit. (Find N when PW = 0) year period.
