Kayla and Camille, both teachers, are adding books to their class libraries. Kayla’s classroom started out with a collection of only 14 books, but she plans to purchase an additional 2 books per week. Camille‘s library started out with 24 books, and she has enough money in her budget to purchase another 1 book per week. At some point, the two teachers’ libraries will contain the same number of books. How many books will each class have ?
