Question: Cassidy collects movie posters from newly released sci-fi movies. After this summer, she will have six more posters in her collection, making it double the size it was two years ago when she had 14 posters. How many posters does she have now? Think carefully first, then make a decision:
Let C be the number of posters Cassidy has now. After this summer, she will have twice as many posters as when she had 14, so she will have C + 6 = 2 * 14 = 28 posters. Thus, Cassidy has C = 28 - 6 = 22 posters now. So the answer is 22.
