answer part q2,q3,q4,q5,q6 (part one leave it i have the answer) , those are 10 different parts and it's under one questions

The spreadsheet in below sheet is the one Mohamad used to make the decision. York was the clear choice due to its substantially largi value. hence York AC units were installed. During a quick review (year 4 of operation), it was obvious that the maintenance costs and repair savings have not followed (and will not follow the estimates made 4 years ago. 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 years. Also, the electrical power savings for the last 4 years were $31,312( year 1),$27,565(y 2). $30,493 (year3), and $32,903 ( year4), as best as Mohamad can determine. He believes savings will decrease by $3,349 per year hereafte Finally, these 4-year-old AC units are worth nothing on the market now, so the salvage is zero, not $3000.

Q7 - With these new estimates, what is the recalculated Total PW for YORK AC units. 06. If these estimates had heen made 4 years ogo, would YORK still have been the economic choice, why explain your answer. Q9. What is difference in capital recovory amount for the YORK units with those new estimates? Q10 - If MARR is changed to 8% for the upcoming 6 years what wis be the Total PW for the YORK units
