Solve for x.
0.7x = 3276
x = 3276/0.7
x = ??
0.7x = 3276
x = 3276/0.7
x = ??

This is a proportion question. Set up what you know as a proportion.
First of all, they raised $3,276, which is 70% of their goal. You need to know how much more money needs to be raised.
So:
70/100 (which is the fraction form of saying 70%) has to equal 3,276/x. (x is what we are looking for)
Cross multiply:
70 X x (70x) and 3,276 X 100 (327,600)
70x=327,600
Divide by 70 on both sides of the equation:
x=4,680
So we now know that their total money raising goal is $4,680. But the question is how much more money must be raised. Now all you have to do is 4,680-3,276 to get the answer
