Initial Cost = $5000
Annual Fees =$200
Salvage Value = $1000
Life=5 years
Discount Rate=8%
PV of Salvage Value = 1000/(1+8%)^5 = 1000/1.08^5 =1000/1.4693=$680.58
PV of Annual Fees =A*(1-(1+r)^-n)/r
=200*(1-(1+8%)^-50/8%
=200*(1-1.08^-5)/0.08
=200*(1-0.6806)/0.08
=200*0.3194/0.08
=798.54
Hence Present Worth = Initial Cost+PV of annual Fee-salvage value
=5000+798.54-680.58 = $5117.96

5b) A Computer costs $8,000. After 5 years, the salvage or resale value is $1000. Annual maintenance cost of software, hardware and upgrades is $500. Annual benefits are $2000. If the interest rate is 12%, compute the annual worth of the computer system. 2
A new oil pump costs $7,500 and has no salvage value once installed. The manufacturer's warranty will pay the 1st year maintenance and repair costs. In the 2nd year, costs will be $900, and they will increase on a $700 arithmetic gradient in subsequent years. Also operating expenses for the pump will be $500 the first year and will increase on a $200 arithmetic gradient in the following years. If interest rate is 8%, compute the pump's equivalent annual cost...

1. A new pipeline is installed. Annual maintenance and pumping costs are considered to be paid in their entireties at the end of the years in which their costs are incurred (assume that maintenance happens in year 10). The pipe has the following costs and properties: Initial cost $7,500 Annual interest rate 5% Service life 10 years Salvage value $500 Annual maintenance $500 Pump cost/hour $2.75 Pump operation 2000 hours/year What is the equivalent uniform annual cost (EUAC) of the pipe?
The annual maintenance costs associated with a machine are $1000 for the first 10 years and $2000 thereafter. The machine has a 30 year life. What is the present worth of the annual disbursements if the interest rate is 12%?
Aroad's maintenance costs $30,000 annually. Redoing the surface would reduce annual maintenance to $5000 per year for 5 years, and to $15,000 per year for the next 5 years. Then maintenance costs return to $30,000 annually. If the interest rate is 6% per year, what is the maximum first cost that can be justified?
3.10 A company purchased new equipment for $250,000 now, that will require annual operations and maintenance (O&M) costs of $30,000 per year for 5 years starting 3 years from now. What is the present worth of these costs if the interest rate is 8% per year?
7. (10 points) A new production machine costs $120,000 and will have a $10,000 salvage value when disposed of in ten years. Annual repair costs are expected to be $0 in years 1, 2, 3 and 4, $5000 in year 5, $5500 in year 6, $6000 in year 7, $6500 in year 8, $7000 in year 9, and $7500 in year 10. If interest is 10%, what is the equivalent uniform annual cost of the new machine?
5.(20 pts) A special power tool for plastic products is classified $6,500, has a salvage value of $800 when sold at the end of 5 years, uniform annual end-of-ycar benefits (before tax) of $3,500 per year, and uniform annual operating and maintenance costs (before tax) of $1,200 per year. Compute the after-tax present worth (for an MARR of 10% ) , based on MACRS depreciation and a 34% corporate income tax rate. (MACRS percentages for a three-year property are 33.33%,...
