= (12b)/(x)/(x-12) = (12b)/[(x) (x-12)] = (12b)/(x^2-12x)

Hallo M8,
When no quitters each person should donate -b/x dollars, 12 qiutters b/(x-12). The remaining people should donate b/(x-12)-(b/x) more or 12b/[x*(x-12)]

I am getting yet another ans

Let y be the additional amt people have to donate.

We know that the total amt should be the same.

ie. xb = (x-12)(b+y)
xb = xb +xy -12b -12y
xy - 12y =12b
y(x-12) = 12b


y = 12b/(x-12)

Oh yes, I got my mistake !!!
I misinterpreted the question !!
I thought x people each paid $b to raise a total of xb !

:( :(

Anyway, now that I understood..
For x people, amt = $b
For 1 person amt = b/x

For x-12 people, amt per person = b/(x-12)

Difference = b/(x-12) - b/x = 12b/[x(x-12)]

This is the amount that each person will pay more. But the question says that To keep the planning amount, how much more would the remaining people donate?.
If its asking how much more would each person donate, then the aswer is 12b/[x(x-12)]
But, if it's saying that how much more remaining people donate, the answer would be 12b/x.

What is OA?
