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.
7) A machine costing $25,000 to buy and $3,000 per year to operate will save mainly labor expenses in packaging over six years. The anticipated salvage value at the end of six years is $5,000. What is the minimum savings in labor the machine should provide at a MARR of 10%? SHOW YOUR WORK FOR CREDIT A) $7,015 B) $8,119 C) $8,092 D) $6,025
solve it using manual computation; do not use Microsoft Excel The Ajax Corporation has an overhead crane that has an estimated remaining life of 10 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 10% per year in evaluating investment alternatives. Should the company replace the old crane?
Your company is considering the purchase of a 30-tonne hoist. The first cost is expected to be $230,000. Net savings will be $38,000 per year over a 12-year life and will be salvaged for $32,715. If the company's after-tax MARR is 8% and it is taxed at 45%, what is the future worth (FW) of this project? Note: You will have to calculate the CCA depreciation rate from the information provided.
The following pair of assets differ only in the MARR. The problem asks you to determine the effect of this difference on the economic life and to explain the result. All assets decline in value by 20 percent of current value each year. Installation costs are zero for all assets. Further data concerning the four pairs of assets are given in the table that follows. Asset First Cost Initial Operating Cost Rate of Operating Cost Increase MARR A $120,000 $30,000 12.5% 5% B $120,000 $30,000 12.5% 25% a. Determine the economic lives for assets A and B. The economic life of asset A is (enter your response here) years, and the economic life of asset B is (enter your response here) years. b. Create a diagram showing the EAC(capital), the EAC(operating), and the EAC(total) for assets A and B. c. Explain the difference in economic life between A and B.

Individual industries will use energy as efficiently as it is economical to do so, and there are several incentives to improve the efficiency of energy consumption. To illustrate, consider the selection of a new water pump. The pump is to operate 800 hours per year. Pump A costs $2,000, has an overall efficiency of 80.58%, and it delivers 11 hp. The other available altemative, pump B, costs $1,200, has an overall efficiency of 44.39%, and delivers 12.8 hp. Both pumps have a useful life of five years and will be sold at that time. (Remember 1 hp = 0.746 kW.) Pump A will use SL depreciation over five years with an estimated SV of zero. Pump B will use the MACRS depreciation method with a class life of three years. After five years, pump A has an actual market value of $410, and pump B has an actual market value of $180. Using the IRR method on the after-tax cash flows and a before-tax MARR of 20%, is the incremental investment in pump A economically justifiable? The effective income tax…
A new machine will cost $200,000. 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). Please provide a written statement clearly…

A company wants to renew its old natural gas fired boiler. According to the receivedprice offer, the new boiler is 400,000 TL in cash. The natural gas consumption of this boiler is 15m3/hour and the price of natural gas is 1.1 TL/m3. The annual real price escalation of natural gas is determined as 1%. The annual cost of the boiler operation and maintenance costs is 25,000 TL and the annual escalationvalue is 17%. By purchasing a new boiler, some of the costs of the old boiler will be saved. The old boiler has costs of 250,000 TL increasing by 15% annually. The new boiler will run for 6,000 hours a year. The annual discount rate is 24% and the annual inflation rate is 17%. Determine whether it is economically feasible to purchase the new boiler by using the annual worthmethod, taking into account the 10-year costs and savings. Use real ratesfor relevant parameters in calculations.
A young engineer is considering establishing his own small company. An investment of P400,000 will be required which will be recovered in 15 years. It is estimated that sales will be P800,000 per year and that operating expenses will be as follows. 1. Materials. Labor Overhead Selling expense P160,000 per year P280,000 per year P40,000 + 10% of sales per year P60,000 The man will give u his regular job paying P216,000 per year and devote full time to the operation of the business; this will result in decreasing labor cost by P40,000 per year, material cost by P28,000 per year and overhead cost by P32,000 per year. If the man expects to earn at least 20% of his capital, should he invest?
Raytheon wishes to use an automated environmental chamber in the manufacture of electronic components. The chamber is to be used for rigorous reliability testing and burn-in. It is installed for $1.4 million and will have a salvage value of $200,000 after 8 years. Its use will create an opportunity to increase sales by $650,000 per year and will have operating expenses of $250,000 per year. Corporate income taxes are 40 percent. Develop tables using a spreadsheet to determine the ATCF for each year and the after-tax PW, AW, for 8 years. After-tax MARR is 10 percent. Use 7- years class depreciation for MACRS and IRR if the chamber is kept
