Question Completion Status: CASE STUDY ANNUAL WORTH ANALYSIS-THEN AND NOW Background and Information Mohamad, owner of an residential furnished apartment's in Dubai, performed an economic analysis 4 years ago when he decided to place an new eefficient central AC unit for each apartments instead of old split units windows type in each room. The estimates used and the annual worth analysis at MARR - 12% are summarized below. Two different AC brands were compared. W/FW LG York Cost and installation, -26,000-30,000 Annual maintenance cost. per year -300 -300 Salvage value, $ 2,000 3,000 Electrical power savings. $ per year 25,000 35,000 Useful life, years 7 10 tions The spreadsheet in below sheet is the one Mohamad used to make the decision. York was the clear choice due to its substantially larger AW value, hence York AC units were installed.

In fact, the maintenance contract cost is going from $300 this year [year 4 to $1200 per year next year and will then increase 9% per year for the next 6 vears. Also, the electrical power savings for the last 4 years were $31,312 ( year 1), $27,565 (year 2). $30,4934 year3), and $32,903 year), as best as Mohamad can determine. He believes savings will decrease by $1.500 per year hereafter. Finally, these 4-year-old AC units are worth nothing on the market now, so the salvage is zero, not $3000. Q1.
