Answer 1

At least 40 dollars per student

Answer 2

first, take 2100 and subtract 1180 from it, this will give you how much they have left to raise
second, divide the number you just got by 23, this will give you how much each student has ro raise.

so, doing this, you get 40, so each student will have to raise $40.
