Question 531668: Question:
Members of the computer club were assessed equal amounts to raise $1200 to buy some software. When 8 new members joined, the per-member assessment was reduced by $7.50. What was the new size of the club?
Stuff I got so far:
Let n= number of members after 8 joined
n-8= number of members before 8 joined
1200/n - ?/(n-8) =7.50
I don't know what I put in the question mark spot! I can solve it I just need to finish setting it up.

You can put this solution on YOUR website!
the cost of the software doesn't change, only the number of members

(1200 / n) - [1200 / (n - 8) = 7.50
