Find the conventional payback period for the following project: First Cost $10,000 $500 in Year 1, increasing by $200/year $3,000/year $4,000 Maintenance Income Salvage Useful Life 10 years MARR 10%
Compare the alternatives below on the basis of their capitalized costs. Assume the MARR is 10% per year, compounded annually Project A Project B Project C First cost ($200,000) ($275,000) ($800,000) Annual income $60,000 $70,000 $80,000 Salvage value $40,000 $60,000 $500,000 Life, years 4 7 infinity
Your firm is currently paying $3,000 a year to a commercial garbage collection agency to haul waste paper to the city dump. The paper could be sold as waste paper if it were baled and strapped. A paper baler is available at the following conditions: Purchase price = $6,500 Labor to operate baler = $3,500/year Strapping material = $300/year Life of baler = 30 years Salvage value = $500 MARR = 10%/year If it is estimated that 500 bales would be produced per year, what would the selling price per bale to a wastepaper dealer have to be to make this project acceptable? Assume no inflation.

Company X is considering the purchase of a helicopter for connecting services between their base airport and the new inter-county airport being built about 30 miles away. It is believed that the chopper will be needed only for 6 years until the Rapid Transit Connection is phased in. The estimates on two types of helicopters under consideration, The Whirl 2 B and The ROT 8, are given below: The Whirl 2 B First Cost Annual Maintenance Salvage Value Useful life in years $95,000 $3,000 $12,000 The ROT 8 $120,000 $9,000 $25,000 6 3 Assuming that the Whirl 2B will be available in the future with identical costs, what is the annual cost advantage of selecting The Whirl 2B ? (Use an interest rate of 10 %) A. cost more than $4,000 C. cost between $4,000 and $3,000 B. save between $3,000 and $2000 D. save more than $4,000

Problem 05.024 Alternative Comparison - Different Lives You and your partner have become very interested in cross-country motorcycle racing and wish to purchase entry-level equipment. You have identified two alternative sets of equipment and gear. Package K has a first cost of $250,000, an operating cost of $5,500 per quarter, and a salvage value of $30,000 after its 2-year life. Package L has a first cost of $170,000 with a lower operating cost of $3,500 per quarter and an estimated $25,000 salvage value after its 4-year life. Which package offers the lower present worth analysis at an interest rate of 8% per year, compounded quarterly? The present worth of package K is $[ and that of package L is $[ (Click to select) offers the lower present worth.
YOUR QUESTION IS: 2. Three mutually exclusive design alternatives are being considered. The estimated sales and cost data for each alternative have been tabulated. The MARR is 20 per year. Annual revenues are based on the number of units sold and the selling price. Annual expenses are based on fixed and variable costs. Determine which selection is preferable based on F W. Confirm your selection by separately checking is preferable using PW.
