DS Question - inequality/absolute value

[WesleyM612]

My sincerest apologies if this has already been posted. I tried searching, but didn't see it. If it has been addressed, can you please point me to that question (or one similar)? I cannot grasp the concept behind the below problem and looking for some guidance.

This DS problem comes from the GMATPrep Software (Problem # QDS04648).

My biggest issue is simplifying the equation in the question stem - and then of course solving the problem.

Any help/guidance would be MUCH appreciated.

Thank you!

We'll be glad to help you with this one, but please post it in the GMAT Prep folder rather than General Math.

...and you need to ask something specific about the problem. you can't just post the problem and say "i don't know how to solve this".

thanks.
