please answer this in steps asap thanks

A project has a total allocated budget of $500$ K AED and a planned duration of $250$ days. The project has been running for $100$

days and it estimated that the actual cost amounts to $200$K AED. Looking at the project deliverables, you have identified that

up to the current date $400$ units out of the total $1200$ units have been delivered.

Perform an EVA of the project at this date. Determine the below parameters:

EVA of the Project at Day $100$:

The Istimate At Completion $($ AC $)$ is the expected total cost of completing all the work.

The fstimate To Completion $($CTC$)$ is the expected cost to finish all remaining work. ETC $=$ EAC $-$ AC

The Variance At Completion $($VAC$)$ is the estimated difference in cost at the completion of the project. VAC $=$ BAC $-$ EAC.

Assuming the future work from Day $100$ onwards will be completed at the planned rate, EAC is given by

EAC$=$BAC$+($AC$=$EV$).$

Determine EAC, as well as ETC and VAC.

$50$ days later, you decide to perform an EVA of the project. The accounting team informs you that the actual conts have now

reached $350$ K AED. $200$ additional units have been dellvered.

Perform an EVA of the project at this date. Determine the below parameters:

EVA of the Project at Day $150$:

Assuming the remaining work from Day $150$ onwards will be influenced by both the SPI and CPI, EAC is given by

EAC$=$AC$+($BAC$-$EV$////($CPI$**$SP$1).$

Determine EAC, as well as ETC and VAC.

The To$-$Complete$-$Performance Index $($TCPI$\_$BAC$)$ indicates the efficiency that must be maintained in order to complete your

project as oriefinally planned.

TCPI$\_$BAC $=($BAC$-$EV$)//($BAC$-$AC$)$

Determine TCPI$\_$BAC. What are your thoughts on how to interpret the TCPI? Is having a TCPI $>1$ good news or bad news $?$

$50$ days before the project deadline, you perform a final EVA of the project. The actual cost has reached $95\%$ of the original

budget. Only $60$ units remain to be delivered.

Derform an EVA of the project at this date. Determine the below parameters;

EVA of the Project at Day $200$:

Assuming the CPI will remain the same for next $50$ days, EAC is given by

EAC$=$BAC$//$CPI

Determine EAC, ETC and VAC.

The To$-$Complete$-$Performance index $($TCP$\_$EAC$)$ indicates the efficiency that must be maintained in order to complete your

project as per the latest tacestimate.

TCR$\_$EAC $=($BAC$-$EV$)//($EAC$-$AC$)$

What are your thoughts on how to interpret the sign of VAC? is positive VAC good news or bad news?
