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?

Consider these two alternatives.Alternative A Alternative BCapital investment OMR 6000 7500Annual revenues OMR 1800 2250Annual expenses OMR 500 750Estimated market valueOMR1200 1600Useful life 10 10MARR 12% 1. Recommend which alternative should be selected.2. How much capital investment of the expensive alternative have to vary so that theinitial decision would be reversed.

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)

1.) Clinix is considering four independent projects. Given: All the projects will be economically viable for only 10 years; Company’s MARR = 12% per year Find: Which project should be selected based on a present worth analysis. *Note* Financial values are in $1,000 units. Project A Project B Project C Project D First Cost ($) -2,700 -1,400 -10,000 -9,500 Annual Net Profit ($/year) 800 1,200 2,400 3,200 Salvage Value ($) 25 30 45 60

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.

Given the two machines’ data                                 Machine  A          Machine B First Cost                P8,000.00            P14,000.00 Salvage value         0                           2,000.00 Annual operation       3,000.00             2,400.00 Annual maintenance   1,200.00           1,000.00 Taxes and insurance   3%                       3% Life, years                   10                          15 Money is worth at least 16% Using equivalent uniform annual cost method, determine the value of alternative A and alternative B: ANSWER for ALTERNATIVE A: Blank 1 ANSWER for ALTERNATIVE B: Blank 2

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.

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

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.
