Four thousand and one. I'm English, so I use the 'and'.
Would any americans say fourty-hundred and one? The way some of you guys don't talk in thousands intruiges me - 'Ten hundred dollars', etc.
Never heard anyone use "ten hundred dollars" instead of a thousand. It would be like using "5 feet 12 inches" instead of just "6 feet."
This.
LiamR, people here (well, those I hear) don't say "ten hundred", because "thousand" is there and easier. But we do say "eleven hundred" for 1100 or "twenty-five hundred" for 2500 or "seventeen fifty" for 1750 (and for $17.50). Makes sense if you consider that "thousand" is only two syllables.
