To decrease the costs of operating a lock in a large river, a new system of operation is proposed. The system will cost $830,000 to design and build. It is estimated that it will have to be reworked every 10 years at a cost of
$120,000. In addition, an expenditure of $80,000 will have to be made at the end of the fifth year for a new type of gear that will not be available until then. Annual operating costs are expected to be $70,000 for the first 15
years and $100,000 a year thereafter. Compute the capitalized cost of perpetual service at i= 7%.

Maintenance money for an athletic complex has been sought. Mr. Kendall, the Athletic Director, would like to solicit a donation to cover all future expected maintenance costs for the building.
These maintenance costs are expected to be $1.2 million each year for the first five years, $1.6 million each year for years 6 through 10, and $1.9 million each year after that. (The building has an
indefinite service life.)
If the money is placed in an account that will pay 7% interest compounded annually, how large should the gift be?

- Barbour Electric is considering the introduction of a new product. This product can be produced in one of several ways: (a) using the present assembly line at a cost of $20 per unit, (b) using the current assembly line after it has been overhauled (at a cost of $5,000) with a cost of $18 per unit; and (c) on an entirely new assembly line (costing $30,000) designed especially for the new product with a per unit cost of $15. Barbour is worried, however, about the impact of competition. If no competition occurs, they expect to sell 10,000 units the first year. With competition, the number of units sold is expected to drop to 6,000. At the moment, their best estimate is that there is a 40% chance of competition. They have decided to make their decision based on the first-year sales. (a) Develop a decision table showing the payoffs. (b) What decision should they make? Hint: develop an EOL table and make a decision based on this table.arrow_forwardA manufacturing company is considering a capacity expansion investment at the cost of $32,850 with no salvage value. The expansion would enable the company to produce up to 30,000 parts per year and the useful life of the additional capacity is seven years. Each part would generate $2.54 net profit and annual operating and maintenance costs are estimated at $8,989 per year. The market demand for the parts is unlimited. All parts produced will be sold. The MARR of the firm is 10%. What is the minimum annual production rate to make this investment justified? Enter your answer as follows: 12345 Round your answer.

Its maximum useful life is 8 years. The expected market value (MV) of the machine at the end of year 1 is $100,000, and it is expected to decline by $15,000 each year afterwards. The annual operating cost (AOC) is projected to be $75,000 during the first year of operation, and it is expected to rise by 15% every year afterwards. Assuming 11% minimum attractive rate of return, calculate the economic service life of the machine. Your calculations need to include a table with the following columns: Year, MV, AOC, Capital Recovery, Annual Worth (AW) of AOC, and Total AW. Illustrate your analysis with a properly labeled chart, featuring the number of years of service on the horizontal axis, and capital recovery, annual worth of the AOC, and total annual worth on the vertical axis (click to format the vertical axis and check the box “Values in reverse order” so that the axis displays rising cost as movement up).

- A small aerospace company is evaluating two alternatives: the purchase of an automatic feed machine and a manual feed machine for a finishing process. The auto feed machine has an initial cost of $23,000, an estimated salvage value of $4000, and a predicted life of 10 years. One person will operate the machine at a rate of $12 per hour. The expected output is 8 tons per hour. Annual maintenance and operating cost is expected to be $3500. The alternative manual feed machine has a first cost of $8000, no expected salvage value, a 5-year life, and an output of 6 tons per hour. However, three workers will be required at $8 per hour each. The machine will have an annual maintenance and operation cost of $1500. All projects are expected to generate a return of 10% per year. How many tons per year must be finished to justify the higher purchase cost of the auto feed machine?arrow_forwardA contractor has purchased a wheel loader for $115,000 and plans to use it for 2,000 hours per day. The cost of one set of tires is $25,000. At this usage rate, the contractor anticipates disposing of the loader after using it for 10 years and realizing a salvage value of $35,000. The flywheel horsepower rating of the loader's diesel engine is 105 horsepower. The interest rate is 10%. The loader operator will earn $34.00 per hour including fringe benefits, and diesel fuel costs $1.20 per gallon. How much is the contractor's hourly ownership cost for the loader if using time value money analysis?arrow_forwardThe Riteway Ad Agency provides cars for its sales staff. Its present fleet of cars is three years old and will be sold very shortly. To provide a replacement fleet, the company is considering two alternatives: Purchase alternative: The company can purchase the cars and sell them in three years. Ten cars would be purchased for $15,000 each. If this alternative is chosen, the entire fleet will incur the following costs: Annual cost of servicing, taxes, and licensing $ 3,100 Repairs, first year $ 1,000 Repairs, second year $ 3,500 $ 5,500 Repairs, third year At the end of three years, the fleet could be sold for one-half of the original purchase price. Lease alternative: The company can lease the cars under a three-year lease contract costing $50,000 per year (the first payment due at the end of Year 1). As part of this lease agreement, the owner would provide all servicing and repairs, license the cars, and pay the taxes.

- You are considering a hydraulic excavator. This machine will have an estimated service life of 10 years, with a salvage value of 10% of the investment cost. Its expected savings from annual operating and maintenance costs are estimated to be SR 60,000. To expect a 14% rate of return on investment, what would be the maximum amount that you are willing to pay for the machine: (Choose the closest answer) Hint: solve for the capital cost (I) by equating recovery cost (CR) with operating and maintenance cost (OC). a) SR 297,594 b) SR 355,104 c) SR 250,417 d) SR 321,643 e) SR 356,218arrow_forwardYour firm is considering purchasing an old office building with an estimated remaining service life of 20 years. Recently, the tenants signed a long-term lease, which leads you to believe that the current rental Income of $ 250,000 per year will remain constant for the first five years. Then the rental income will increase by 10% for every five-year interval over the remaining life of the asset. That is, the annual rental Income would be $ 275,000 for years 6 through 10, $ 302,500 for years 11 through 15 and $ 332,750 for years 16 through 20. You estimate that operating expenses, including income taxes, will be $ 80,000 for the first year and that they will increase by 5% each year thereafter. You also estimate that razing the building and selling the lot on which it stands will realize a net amount of $ 50,000 at the end of the 20- year period., What would be the maximum amount you would be willing to pay for the building and lot at the present time with an interest rate of 12% per…arrow_forwardO.arrow_forward
