Biomet Implants is planning new online patient diagnostics for surgeons while they operate. The new system will cost $300,000 to install in an operating room, $5000 annually for maintenance, and have an expected life of 10 years. The revenue per system is estimated to be $80,000 in year 1 and to increase by $10,000 per year through year 10.
a) Determine NPV to see if the project is economically justified using PW analysis and an MARR of 10% per year.
b) Insert a Triangle distribution with minimum at $8000, average 10,000 and maximum at 12000 as the input distribution for the revenue increase. Perform Monte Carlo Simulation and discuss the results.
A land development company is considering the purchase of earth-moving equipment. The equipment will have a first cost of $190,000 and a salvagevalue of $70,000 when the company sells it in 10 years. A service contract for maintenance on the equipment will cost $40,000 per year. The operatingcost is expected to be $260 per day. Alternatively, the company can rent the necessary equipment for $1100 per day and hire a driver at $180 per day. If the company’s MARR is 10% per year, how many days per year must the company need the equipment in order to justify its purchase?
Because of international competition, a company that manufactures high-speed submersible rotary indexing spindles must upgrade its production equipment to reduce costs over a 6-year planning horizon. The company can invest $80,000 one year from now, 2 years from now, or 3 years from now. Depending on when the investment is made, the savings will vary. That is, the savings will be $29,000, 34,000, or $38,000 per year if the investment is made 1, 2, or 3 years from now, respectively.

Please provide excel formula.arrow_forwardEP Electric has identified two new methods to treat its cooling water. Alternative I (for inflow) would treat the raw water with a conventional reverse osmosis system so that the cycles of concentration could be increased from 5 to 20. This will result in water cost savings of $360,000 per year and chemical cost savings of $56,000 per year. The initial cost of the equipment will be $2.3 million with an operating cost of $125,000 per year. Alternative B (for blowdown) will treat the cooling tower blowdown water using a highpressure seawater reverse osmosis system to recover most of the water that is sent to an evaporation pond. This option will result in water savings of $270,000 per year. The cost of the system will be $1.2 million with an operating cost of $105,000 per year. Assuming one of the two methods must be installed, determine which is preferred on the basis of the incremental ROR value using MARR of 5% per year, which is a typically low return expected of government projects.…arrow_forwardTwo roadway designs are under consideration for access to a permanent suspension bridge. Design 1A will cost $3 million to build and $100,000 per year to maintain. Design 1B will cost $3.5 million to build and $40,000 per year to maintain. Both designs are assumed to be permanent. Use an AWbased rate of return equation to determine (a) the breakeven ROR, and (b) which design is preferred at a MARR of 10% per year.arrow_forward
- Lego Group in Bellund, Denmark, manufactures Lego toy construction blocks. The company is considering two methods for producing special-purpose Lego parts. Method 1 will have an initial cost of $460,000, an annual operating cost of $100,000, and a life of 3 years. Method 2 will have an initial cost of $560,000, an operating cost of $90,000 per year, and a 6-year life. Assume 11% salvage values for both methods. Lego uses an MARR of 9% per year.

Alternative A is an in- crease in TV and radio marketing. A total of $300,000 spent now is expected to increase revenue by $60,000 per year. Alternative B requires the same investment for enhancements to the in-plant manufacturing process that wil improve the temperature retention properties of the seals around each glass pane. New revenues start slowly for this alternative at an estimated $10,000 the first year, with growth of $15,000 per year as the improved product gains reputation among builders. The MARR is 8% per year and the maximum projection period is 10 years for either alternative.arrow_forwardThe Texas Department of Transportation (TxDOT) is considering two designs for crash barriers along a reconstructed portion of I-10.

- A company that manufactures high-speed submersible rotary-indexing spindles is considering an upgrade of production equipment to reduce costs over the next 5 years. The company can invest $80,000 now, 1 year from now, or 2 years from now. Depending on when the investment is made, the savings will vary. The saving estimates are $26,000, $31,000, or $37,000 per year if the investment is made now, 1 year from now, or 2 years from now, respectively. The company will only invest if the ROR is at least 20% per year. Using a future worth analysis, determine if the timing of the investment will affect the return requirement and, if so, when the investment should be made. Solve by (a) hand, and (b) spreadsheet.arrow_forwardTwo methods can be used for producing expansion anchors. Method A costs $80,000 initially and will have a $15,000 salvage value after 3 years. The operating cost with this method will be $30,000 per year. Method B will have a first cost of $120,000, an operating cost of $8000 per year, and a $40,000 salvage value after its 3-year life. At the MARR of 12% per year, which method should be used on the basis of a present worth analysis?arrow_forwardRent-A-Wreck car rental agency has a contract with PM Warranty, Inc. to do major repairs for $700 per car. The car rental agency estimates that it could repair its own cars for $300 each if it acquires a facility for $300,000 now. A salvage value of $40,000 after 15 years is estimated for the facility. What is the minimum number of cars that must be repaired each year to make the acquisition attractive at an interest rate of 10% per year?arrow_forward
- A process can be completed using either Alternative X or Y, where Y is an automated version of X. Alternative X has fixed costs of $10,000 per year with a variable cost of $50 per unit. If the process is automated, the fixed cost for Y will be $5,000 per year and its variable cost will be only $30 per unit. The minimum number of units that must be produced each year for alternative Y to be favored is closest to:a. Alternative Y will be favored for any level of productionb. 125c. 375d. Alternative X will be favored for any level of productionarrow_forwardA piece of new equipment has been proposed by engineers to increase the productivity of a certain manual welding operation. The investment cost is 2,500,000, and the equipment will have a market value of 50,000 at the end of a study period of 15 years. Increased productivity attributable to the equipment will amount to 500,000 per year after extra operating costs have been subtracted from the revenue generated by the additional production. If the firm’s Minimum Attractive Rate of Return is 22% per year, is this proposal a sound one? Use the Present Worth Method and Annual Worth Method.arrow_forwardIn order to provide drinking water as part of its 50-year plan, a west coast city is considering constructing a pipeline for importing water from a nearby community that has a plentiful supply of brackish ground water. A full-sized pipeline can be constructed at a cost of $122 million now. Alternatively, a smaller pipeline can be constructed now for $80 million and enlarged 20 years from now for another $100 million. The pumping cost will be $25,000 per year higher for the smaller pipeline during the first 20 years, but will be approximately the same thereafter. Both pipelines are expected to have the same useful life with no salvage value. (a) At an interest rate of 6% per year, which alternative is more economical? (b) Write the spreadsheet function to display the PW for the smaller pipeline alternative.arrow_forward
