vieestchienWhen you present yourself, do you say "I'm a salesperson" or "I'm a salesman"? How about "I'm a saleswoman"?

275: two hundred and seventy five or two hundred seventy five? The first is standard; the second is also heard often.

1210: a thousand two hundred and ten? a thousand and two hundred and ten? Not the second one.
