Hello Mike! This is thunderlord
This is the question from the 2010-2011 SAT section 6 #8
The table above shows the number of consecutive nights that each of five families stayed a t a certain hotel during a 14- night period.
The days the Liu’s family’s stay,the Benton family’s stay, and Jackson family’s stay (longest) do not overlap are after days 9 isn’t it? So shouldn’t it be on the 10th day since neither family’s stay are there except for the Jackson’s?
I think you’re missing a few words in your question, but I know the problem you’re talking about. I’ve handled it here on the Tumblr Q&A.
