+9479 If you had a bag of cookies and I ate one, and there were only 3 cookies left, how many cookies were in the bag before I ate one?
If you had a bag of cookies and I ate 28 of them, and there were only 33 cookies left, how many cookies were in the bag before I ate 28 of them?
Maybe if you think about it in terms of cookies you can figure it out. :)
