ANNUAL WORTH ANALYSIS-THEN AND NOW Background and Information Mohamad, owner of an residential fumished 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. The spreadsheet in below sheet is the one Mohamad used to make the decision. York was the clear choice due to its substantilly 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 7% per year for the next 6 yoars. Aso, the electrical power savings for the last 4 years were $31,312( year 1 ), $27,565 (year 2). $30,493 (year 3 ) and $32,903 ( year4), as best as Mohamad can delermine. He believes savings will decrease by $3,349 per year hereatter. Finaly, these 4-year-old AC units are worth nothing on the market now, so the salvage is zero, not $3000 Q1 - With these new estimates, What is the AW of the Investment and Salvage value for YORK AC unit? Q2 - With these new estimates, What is the FW of the Investment and Salvage value for YORK AC unit? Q3 - With these new estimates, what is the recalculated AW maintenance cost for the YORK AC unts?

Q6 - With these new estimates, what is the recalculated Total FW for YOAK AC units. Q7. With these new estimates, what is the recalculated Total FW for YOAKAC units. Q6. If these estimates had been made 4 years ago, would YOFKK stil have been the economic choice, why oxplain your answer 99.
