Question competion Status Mohamad, owner of an residential furnished apartments in Dubai, performed on economic analysis 5 years ago when he decided to place an eweefficient central Cunn for each apartments instead of old split units windows type in each room. The estimates used and the annual worth analysis at MARR 12Ware summarired below. Two different AC brands were compared LG York Cost and installation, -26,000-30,000 Annual maintenance cost per year -100-300 Salvage value, 2,000 3,000 Electrical power savings, 5 per year 25,000 35,000 Useful life years 7 10 The spreadsheet in below sheet is the one Mohamad used to make the decision.

It was obvious that the maintenance costs and repair savings have not followed (and will not follow the estimates made 5 years ago. In fact, the maintenance contract cost is going from $300 this year (year 5) to $1200 per year next year and will then increase 9% per year for the next 4 years up to year 10). Also, the electrical power savings for the last 5 years were 531,312 year 1), 525,565 (year 21, $25.234 year3), 526,903 year4), and $27,345 (years) as best as Mohamad can determine. He believes savings will decrease by $1,200 per year hereafter. Finally, these 5 year old AC units are worth nothing on the market now, so the Salvage in is zero, not $3000. QI-With these new estimates, what is the AW of the investment and Salvage value for YORK AC unit? 7173,07 Q2. With these new estimates.
