Shawana made a schedule for reading books during 4 weeks (28 days) of her summer vacation…
Solution:
We will list the number of days it will take to read each book. Since Shawana does not start a new book the same day she finishes a book, the number of days for her to read a book will be one more than the number of pages of the book divided by 50 (ignoring remainders).
Book 1: 6 days
Book 2: 3 days (Total: 9 days)
Book 3: 3 days (Total: 12 days)
Book 4: 4 days (Total: 16 days)
Book 5: 4 days (Total: 20 days)
Book 6: 1 day (Total: 21 days)
Book 7: 5 days (Total: 26 days)
Book 8: 2 days (Total: 28 days)
So, in 28 days, Shawana will have finished 8 books.
Answer: B
