Final answer:
To determine how many weeks it will take Manny to read the entire book, we rely on the division of the total number of chapters (28) by the number of chapters read per week (7), which equals 4 weeks.
Step-by-step explanation:
To find out how long it will take Manny to read the book, we need to use the information provided that Manny reads 7 chapters each week and that the book has 28 chapters in total. The fact that will help you determine how many weeks it will take Manny to finish reading the book is the division of the total number of chapters by the number of chapters he can read per week. So, the useful facts from the options given are:
- B- 4x7=28
- D- 28 divided by 7=4
- E- 7x4=28
These facts show that when you divide 28 (the total number of chapters) by 7 (the number of chapters Manny reads every week), you get 4, which means Manny will take 4 weeks to read the entire book.
