50% (02:00) correct
50% (00:03) wrong based on 3 sessions
At a certain conference, 72% of the attendees registered at least two weeks in advance and paid their conference fee in full. If 10% of the attendees who paid their conference fee in full did not register at least two weeks in advance, what percent of conference attendees registered at least two weeks in advance? (A) 18.0% (B) 62.0% (C) 79.2% (D) 80.0% (E) 82.0%
Thanks for clarifying. I was getting extremely frustrated with the fact that it was not clear to me even after seeing the orig. solution and was hoping that I was right in thinking that the question was not complete.
