An injection-molding machine has a first cost of $1,050,000 and a salvage value of $225,000 in any year. The maintenance and operating cost is $235,000 with an annual gradient of $75,000. The MARR is 10%. What is the most economic life?

the process for producing a fruit-tree pesticide has a first cost of $200,000 with annual costs of $50,000 and revenue of $90,000 per year. What is the payback period in years?

Costs associated with the manufacture of miniature high-sensitivity piezoresistive pressure transducers is $85,000 per year. A clever industrial engineer found that by spending $19,000 now to reconfigure the production line and reprogram two of the robotic arms, the cost will go down to $52,000 next year and $58,000 in years 2 through 5. Using an interest rate of 15% per year, determine the present worth of the savings due to the reconfiguration. The present worth of the savings is determined to be $

Machine A costs $1,520,000 to buy and install and costs $48,000 per year to operate. The machine has a five-year useful life and zero salvage value. The required return is 15.5%. What is the equivalent annual cost of Machine A? (Answer: $506,819)

Your IT company is working on a four-month project for a local mining company. The total planned value of the project (BAC) is $600,000. You are at the end of month three.  By the end of month three you scheduled to spend $500,000(PV). The actual cost through this three-month mark is $450,000 (AC). The total work completed at the end of month three is 94 percent.   Calculate the earned value, EV=

please as soon as possible . thank you

Two techniques can be used to produce expansion anchors. Technique A costs $90,000 initially and will have a $12,000 salvage value after 3 years. The operating cost with this method will be $33,000 in year 1, increasing by $2600 each year. Technique B will have a first cost of $113,000, an operating cost of $7000 in year 1, increasing by $7000 each year,and a $43,000 salvage value after its 3-year life. At an interest rate of 13% per year, which technique should be used on the basis of a present worth analysis? Notice that there are no revenues.   Please work out and do not use excel, however if you use excel please show how to input everything needed down to the formula, thank you!
