Yes, DS has missed a significant number (ha) of math problems lately involving rounding and the casual use of the word "about". I tied myself in knots trying to figure out what was wrong with his answers when he brought home papers marked wrong, and everything I could see was right! Finally I checked the book to see what he was supposed to be doing, and discovered we were estimating. To the nearest god knows what, because "about" is not helpful.

I would have estimated your problem at 45,600 myself. Although, with the "citizens" question, and depending on where these counties are located, and what time of year it is, it's probably more like 100,000. But only 253 of them vote.
