An airport needs a modern material handling system for facilitating access to and from a busy maintenance hangar. A​ second-hand system will cost​ $75,000. A new system with improved technology can decrease labor hours by​ 20% compared to the used system. The new system will cost​ $150,000 to purchase and install. Both systems have a useful life of five years. The market value of the used system is expected to be​ $20,000 in five​ years, and the market value of the new system is anticipated to be​ $50,000 in five years. Current maintenance activity will require the used system to be operated eight hours per day for 20 days per month. If labor costs​ $40 per hour and the MARR is​ 1% per​ month, which system should be​ recommended?

you're crazy if you think that someone is going to write a 500 word report for you.

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
