Question
Chapter 9, Problem 1P
To determine
Calculate the present worth.
Expert Solution & Answer
Explanation of Solution
Time period is denoted by n and the interest is denoted by i. The present worth (PW) of defender (Old boat) can be calculated as follows.
Annual worth of defender is $4,085.
The present worth (PW) of challenger (New boat) can be calculated as follows.
Present worth is $4,870. Since the present worth of the cost is less for the defender, retain the defender one more year.

Suppose the reader has an old car, which is a gas guzzler. It is 10 years old and could sell for $400 cash to a local dealer. Assume that your MV in two years is zero. For the foreseeable future, annual maintenance expenses will average $800, and the car will get only 10 miles per gallon. Gasoline costs $1.50 per gallon, and the car is used an average of 15,000 miles per year. You now have the opportunity to replace your old car with a better one that costs $8,000. If I bought it, I would pay cash. Maintenance costs are expected to be negligible since it has a two-year warranty. This car averages 30 miles per gallon. Use the IRR method to determine which alternative should be selected. Use a two-year analysis period and assume that the new vehicle can sell for $5,000 at the end of year two. The MARR is 15% per year. Mention any other assumptions you make.
A small manufacturing firm is considering the purchase of a new machine to modernize one of its current production lines. Two types of machines are available on the market. The lives of machine A and machine B are 4 years and 6 years, respectively, but the firm does not expect to need the service of either machine for more than 5 years. The machines have the following expected receipts and disbursements.
Item
Machine A (USD)
Machine B(USD)
First cost
325k
425k
Service life
4 years
6 years
Estimated Salvage Value
30k
50k
Annual Opertaing & Maintenance Costs
40k
26k
Oil Filter Change every other year
5k
NONE
Enginer Overhaul
10k every 3 years
14k every 4 years
The firm always has another option: To lease a machine at 150k a year, fully maintained by the leasing company. After four years of use, the salvage value for machine B will remain at 50k.
How many decision alternatives are there?…
Your company is considering the introduction of a new product line. The initial investment required for this project is $500,000, and annual maintenance costs are anticipated to be $45,000. Annual operating costs will be directly proportional to the level of production at $8.50 per unit, and each unit of product can be sold for $65. If the MARR is 15% and the project has a life of 5 years, what is the minimum annual production level for which the project is economically viable? The equipment can be sold for $80,000 at the end of five years.

The firm is trying to decide whether to purchase trucks with diesel engines or trucks with gasoline engines. The diesel truck will have a useful life of 12 years, after which it will need to be replaced. The diesel truck costs $110,000 to purchase and its annual maintenance and operation costs will depend on the cost of regular maintenance/repairs and the cost of diesel fuel. In Years 1 through 5, its annual maintenance/repair costs are expected to be $2000 per year. In Years 6 through 12, its annual maintenance/repair costs are expected to be $2500 per year. The firm expects that the diesel truck will use 5,900 gallons of diesel fuel per year (Years 1 through 12) and believes that diesel fuel will cost $2.65 per gallon, on average, during the life of the truck. The gasoline truck only costs $60,000 to purchase but will have a useful life of only 4 years, after which it will need to be…arrow_forward
- A California utility firm is considering building a 50-megawatt geothermalplant that generates electricity from naturally occurring underground heal. The binary geothermal system will cost $85 million to build and $6 million (including any income-tax effect) to operate per year. (Unlike a conventional fossilfuel plant, this system will require virtually no fuel costs.) The geothermal plant is to last 25 years. At the end of that time, the expected salvage value will be about the same as the cost to remove the plant. The plant will be in operation for 70% (the plant-utilization factor) of the year (or 70% of 8,760 hours per year).
