To solve the problems using the line graph provided, let's analyze the data step by step.
Line Graph Analysis:
The line graph shows the number of books sold per week over 8 weeks. The x-axis represents the weeks (1 to 8), and the y-axis represents the number of books sold (ranging from 0 to 140).
From the graph:
- Week 1: 60 books
- Week 2: 120 books
- Week 3: 120 books
- Week 4: 90 books
- Week 5: 90 books
- Week 6: 60 books
- Week 7: 90 books
- Week 8: 10 books
Solutions to the Questions:
#### 1) How many books were sold in week 2?
- From the graph, the number of books sold in week 2 is
120.
-
Answer: \( \boxed{120} \)
#### 2) How many books were sold in week 3 and 4?
- Week 3: 120 books
- Week 4: 90 books
- Total for weeks 3 and 4: \( 120 + 90 = 210 \)
-
Answer: \( \boxed{210} \)
#### 3) How many books were sold in week 5, 6, and 7?
- Week 5: 90 books
- Week 6: 60 books
- Week 7: 90 books
- Total for weeks 5, 6, and 7: \( 90 + 60 + 90 = 240 \)
-
Answer: \( \boxed{240} \)
#### 4) How many more books were sold in week 7 than in week 8?
- Week 7: 90 books
- Week 8: 10 books
- Difference: \( 90 - 10 = 80 \)
-
Answer: \( \boxed{80} \)
#### 5) How many books were sold in all 8 weeks?
- Week 1: 60 books
- Week 2: 120 books
- Week 3: 120 books
- Week 4: 90 books
- Week 5: 90 books
- Week 6: 60 books
- Week 7: 90 books
- Week 8: 10 books
- Total: \( 60 + 120 + 120 + 90 + 90 + 60 + 90 + 10 = 640 \)
-
Answer: \( \boxed{640} \)
#### 6) What was the average number of books that were sold each week?
- Total books sold in 8 weeks: 640
- Number of weeks: 8
- Average: \( \frac{640}{8} = 80 \)
-
Answer: \( \boxed{80} \)
Final Answers:
1. \( \boxed{120} \)
2. \( \boxed{210} \)
3. \( \boxed{240} \)
4. \( \boxed{80} \)
5. \( \boxed{640} \)
6. \( \boxed{80} \)
