the answer is 9 smile.png win


May I ask how you came up with that answer? From your question, I generate the following equation

$perPerson = 72,000 / n
4000 = 72,000 / (n-3)

n = 72000/4000 + 3 = 21

So I thought the answer would be 21. Maybe my initial equation is wrong.

If they would be 3 less people

I thought this read as N-3, but what she really means is N/3 ("they would be 3 [times] less people").
