If you put the number in context, I think it would make more sense. As most said, 5,000 = Fifty Hundred. You seem to want to avoid using 5,000 for whatever reason though. I just don't understand why. In the U.S., the term fifty-hundred is generally wrong and I'm guessing most people who heard someone use this expression would probably conclude that the individual is not very smart. I can't think of any sentence where one would use the term fifty-hundred over five thousand. "Scrooge sorted his money at his desk. He made fifty hundred piles." That's about one of the only ways I can think of to use the term fifty hundred and it's pretty horrible. In conclusion, turning a generally unaccepted number into a numeric form isn't very easy. Just use 5,000 instead.
5000 ... Is that what you mean?
So much faith in american education.
5000 is 50 hundred. 1500 is 15 hundred and 2500 is 25 hundred so 5000 is 50 hundred
