An air sampling station can be powered by a solar cell or an electric line. At an interest rate of 10% per year, determine (a) Which alternative should be selected on the basis of an annual worth analysis? (b) what must be the first cost of the other alternative to be equally attractive economically?

A company that manufactures brushless blowers invested $700,000 in an automated quality control system for blower housings. The resultant savings was $180,000 per year for 5 years. If the equipment had a salvage value of $100,000, what rate of return per year did the company make and should the company invest in the blower if MARR is 10%? 7.31% per year (invest in the blower) None of the above 7.31% per year (do not invest in the blower) 12.30% per year (invest in the blower) 12.30% per year (do not invest in the blower)
A coal-fired plant has upgraded an emission control valve. The modification costs only $8000 and is expected to last 6 years with a $200 salvage value. The maintenance cost is expected to be high at $1700 the first year, increasing by 11% per year thereafter. Determine the present worth of the modification and maintenance cost both by hand calculation using formula and by spreadsheet at an interest rate of 8% per year.

A manufacturing company is proposing two new methods to enhance and increase the production line of the company. Method A is expected to cost $1000 while method B is expected to cost $2400. The maintenance cost of the production line will increase to $800 per year if method A is applied and $650 per year with method B, which one of the two proposed methods is more economical based on a future worth analysis at an interest rate of 10% per year? Assume a 15-year life for the production line.
Fairmont Industries primarily relies on 100% equity financing to fund projects. A goodopportunity is available that will require $250,000 in capital. The Fairmont owner can supply themoney from personal investments that currently earn an average of 8.5% per year. The annualnet cash flow from the project is estimated at $30,000 for the next 15 years. Alternatively, 60%of the required amount can be borrowed for 15 years at 9% per year. If the MARR is the WACC,determine which plan, if either is better. This is a before-tax analysis
GoBulls Media is considering opening a new manufacturing facility to process and mail coupons to 660,000 households in the Tampa Bay area. The new facility will require an initial investment of $240,000 and an annual operating cost of $22,000. It will have a $86,500 salvage value after 5 years. Calculate the Effective annual interest rate of the MARR if the company's minimum attractive rate of return is 5% per year, compounded monthly.
An oil refinery finds that it is necessary to treat the waste liquids from a new process before discharging them into a stream. The treatment will cost $20,000 the first year, but process improvements will allow the costs to decline by $2,000 each year. As an alternative, an outside company will process the wastes for the fixed price of $10,000/year throughout the 7 year period, payable at the beginning of each year. Either way, there is no need to treat the wastes after 7 years. Use the annual worth method to determine how the wastes should be processed. The company's MARR is 14%. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 14% per year. The AW of the in-house treatment is $ (Round to the nearest dollar.)
A building project has a present cost of 123,000 JD, an annual cost of 18,000 JD, and a periodic cost of 41,000 JD every 5 years. Use an interest rate of 12% per year to find the capitalized cost of the project.
Concurris Prototyping is committed to using the newest and finest equipment in its labs. Accordingly, Wilma, a senior engineer, has recommended that a 2-year-old piece of precision measurement equipment be replaced immediately. She believes it can be demonstrated that the proposed equipment is economically advantageous at a 15%-per year return and a planning horizon of 5 years. Perform the replacement analysis using the annual worth method, a 5-year study period, and the estimates below. Was Wilma correct?

Equipment needed at Valero Corporation refinery for the conversion of corn stock toethanol, a cleaner burning gasoline additive, will cost $175,000 and have net cashflows of $35,000 the first year, increasing by $10,000 per year over the life of 5 years.Develop a spreadsheet chart that plots AW vs interest rate to show where (what interestrate) the project switches from financially justified to unjustified. Use AW as the verticalaxis of the chart, and interest (i) as the horizontal axis of the chart. Use a range ofinterest rates spanning from 10% to 20%, and use increments of 1%. Label both axesand use a title for the chart.
