TOPIC: Formula Exam Question Clarification

I would like an explanation as to how it is determined from this question below that there was an issue to justify the EAC formula used.

Question 10: PV = 100, EV = 105, BAC = 400, AC = 102 and CV = 3? What is the
Estimate to Complete (ETC) if work will continue at the planned rate?
A) 298
300
C) 305
D) 295
: The formula for calculating the ETC is: ETC = EAC – AC. First, since
estimate at completion does not exist, you must calculate it using the formula
EAC = AC + (BAC – EV) = 102 + (400 – 105) = 397. Once you have the EAC,
you plug the values into the formula ETC = EAC – AC giving you ETC = 397 –
102 = 295

I think the formula used is inappropriate. I think it should be BAC/CPI.

I agree, and that is how I responded initially.

Thanks
