Kate sold 1/2 of her paintings and purchased 7 more. If Kate has 21 paintings now, how many paintings did she have to begin with?

She had 28 paintings to begin with. Because if you take away the 7 that she bought, you would have 14 which we know is half of what she had to begin with. Which means all you have to do is double 14 which means she has 28 paintings.

The answer is 28, 21-7 is 14, 14x2 is 28.
