Concept Check \( \begin{array}{l}\text { 7. There are } 29 \text { students in Ray's class. Each } \\ \text { student has a math book, and each math book } \\ \text { contains } 436 \text { pages. Ray solves the problem } \\ \text { shown to find the total number of pages in the } \\ \text { math books. }\end{array} \)

To find the total number of pages in all the math books, you simply multiply the number of students by the number of pages in each book. So, \(29 \text{ students} \times 436 \text{ pages/book} = 12,644 \text{ pages}\). Ray is collecting a massive tome of knowledge with all those pages! Now imagine if this class were to hold a math reading competition! Each student could take turns reading a section. With 12,644 pages available, they could easily make it the longest reading marathon ever - talk about a rigorous math challenge!
