Ms. Child is considering the purchase of a new food packaging system. The system costs $144166. Ms. Child plans to borrow one-third of the purchase price from a bank at 4.5% per year compounded annually. The loan will be repaid using equal, annual payments over a 7-year period. The system is expected to last 15 years and have a salvage value of $15080 at that time. Over the 15 year period, Ms. Child expects to pay $915 per year for maintenance. The system will save $4558 per year because of efficiencies. Ms. Child uses a MARR of 8% to evaluate investments. What is the equivalent uniform annual worth (EUAW) of this system?
