It looks like this post was victim to the same issue I encountered in one of my posts: HTML encoding thinking that < and > signs were tags. Your post is currently illegible. Could you please post again, and check the "Disable HTML in this post" so that it posts correctly?

Thanks!

Hi there,

I think there is still a typo in the problem. When I try to solve for e given statement 1, this is what I get:

4(e-1) = (4e) – 600 (what you have posted)
4e - 4 = 4e - 600
-4 = -600 .... which is clearly false

Please take another look at the problem and see if something was entered incorrectly. Thanks,

Tatiana

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
