Let’s solve each question step by step by interpreting the
line plot.
---
First, let’s understand the line plot:
The horizontal axis shows the number of books read: from 0 to 7.
Each “X” represents one student who read that many books.
We’ll count the X’s above each number:
-
0 books: 2 X’s → 2 students
-
1 book: 1 X → 1 student
-
2 books: 4 X’s → 4 students
-
3 books: 3 X’s → 3 students
-
4 books: 3 X’s → 3 students
-
5 books: 0 X’s → 0 students
-
6 books: 2 X’s → 2 students
-
7 books: 0 X’s → 0 students

## Now, answer each question:
---
1. How many students were surveyed?
Add up all the X’s:
2 (for 0) + 1 (for 1) + 4 (for 2) + 3 (for 3) + 3 (for 4) + 0 (for 5) + 2 (for 6) + 0 (for 7)
=
2 + 1 + 4 + 3 + 3 + 0 + 2 + 0 = 15 students
✔ Answer: 15

2. How many students read exactly 3 books?
Look at the column for “3”: there are
3 X’s
✔ Answer: 3
---
3. What was the most books read by any student?
Look for the highest number on the axis with at least one X.
- 6 has 2 X’s → so someone read 6 books.
- 7 has 0 X’s → no one read 7.
✔ Answer: 6
---
4. How many more students read 2 books than 1 book?
- Students who read 2 books: 4
- Students who read 1 book: 1
- Difference: 4 – 1 =
3
✔ Answer: 3
---
5. How many students read at least 4 books?
“At least 4” means 4 or more: so 4, 5, 6, 7.
- 4 books: 3 students
- 5 books: 0
- 6 books: 2
- 7 books: 0
Total: 3 + 0 + 2 + 0 =
5
✔ Answer: 5
---
6. How many students didn’t read any books?
That’s “0 books” → 2 students
✔ Answer: 2
---
7. How many students read less than 3 books?
Less than 3 means 0, 1, or 2 books.
- 0 books: 2
- 1 book: 1
- 2 books: 4
Total: 2 + 1 + 4 =
7
✔ Answer: 7
---
8. How many students read more than 5 books?
More than 5 means 6 or 7.
- 6 books: 2
- 7 books: 0
Total: 2 + 0 =
2
✔ Answer: 2
---
## Bonus: How many books were read in all?
We need to calculate the
total number of books read, not the number of students.
Multiply the number of books by the number of students who read that many:
- 0 books × 2 students = 0
- 1 book × 1 student = 1
- 2 books × 4 students = 8
- 3 books × 3 students = 9
- 4 books × 3 students = 12
- 5 books × 0 students = 0
- 6 books × 2 students = 12
- 7 books × 0 students = 0
Now add them up:
0 + 1 + 8 + 9 + 12 + 0 + 12 + 0 =
42 books
✔ Bonus Answer: 42
