9. As part of a class project, Areeb collected $126 in donations for a local hospice. That amount was 7% of the total amount collected by the class.
How much money did the class collect in all?

So you're given that 7% is $126, and you have to find 100%. In order to do this you could set up proportions. 

1) 126/7=x/100

Next you can cross multiply and you'll get:

2) 12600=7x

Now divide each side by 7

3)12600/7=7x/7

And simplify

4)1800=x

Solution: $1800
