Imani is collecting data about the number of books read by students in her class during the summer. The following table shows the number of books read by five students: Carlos - 10 books, Sofia - 15 books, Chen - 8 books, Tatiana - 12 books, and Imani - 20 books. What is the average number of books read by the students in Imani's class?

- 12
- 15
- 10
Why: To find the average number of books read, first add the number of books read by all the students: 10 + 15 + 8 + 12 + 20 = 65. Then, divide the total by the number of students (5): 65 / 5 = 13. Therefore, the average number of books read by the students is 13.
