Total Factors

[Sage Pearce-Higgins]

I'm happy to help you with these problems, but I hope you've read the forum guidelines. First, I should check that these are from the free GMAT Prep tests. If they're from a paid-for resource then, unfortunately, we don't have copyright to post them on our forums.

Second, please ask more specific questions about the problems. What don't you understand? What strategies have you tried? What error did you make?
