Cody was reading through his favorite book series. The series was 54 books in total. If Cody read 6 books the first week, and 3 books the second week and then 9 books every week after that. How many weeks did it take Cody to read his series? Let's think first. Chain of thought:
User
Cody needs to read 54 books - 6 books - 3 books = 45 books. Cody read 9 books each week after = 45 books / 9 books per week = 5 weeks. Cody read for 1 week + 1 week + 5 weeks = 7 weeks total.
Therefore, the answer is 7.
