<human>:  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?
<bot>: Define a variable ** Let C be the number of posters Cassidy has now.
How many posters will she have after this summer? ** 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.
How many posters does she have now? ** Thus, Cassidy has C = 28 - 6 = <<28-6=22>>22 posters now.
