Based on my analysis of the line graph showing books sold per week, I can now answer all the questions:
1. How many books were sold in week 2?
- In week 2, approximately 80 books were sold.
2. How many books were sold in weeks 3 and 4?
- In week 3, approximately 80 books were sold.
- In week 4, approximately 60 books were sold.
- Total for weeks 3 and 4: 80 + 60 = 140 books.
3. How many books were sold in week 5, 6, and 7?
- In week 5, approximately 60 books were sold.
- In week 6, approximately 40 books were sold.
- In week 7, approximately 60 books were sold.
- Total for weeks 5, 6, and 7: 60 + 40 + 60 = 160 books.
4. How many more books were sold in week 8 than week 7?
- In week 8, approximately 20 books were sold (based on the pattern and position on the graph).
- In week 7, approximately 60 books were sold.
- The difference: 60 - 20 = 40 fewer books were sold in week 8 compared to week 7.
- Actually, since the question asks "how many more," and week 8 had fewer books sold, the answer would be negative or we could say 40 fewer books were sold in week 8 than week 7.
5. How many books were sold in all 8 weeks?
- Week 1: ~40 books
- Week 2: ~80 books
- Week 3: ~80 books
- Week 4: ~60 books
- Week 5: ~60 books
- Week 6: ~40 books
- Week 7: ~60 books
- Week 8: ~20 books
- Total: 40 + 80 + 80 + 60 + 60 + 40 + 60 + 20 = 440 books
6. What was the average number of books that were sold each week?
- Total books sold: 440
- Number of weeks: 8
- Average: 440 ÷ 8 = 55 books per week
Therefore, the answers are:
1. 80 books
2. 140 books total for weeks 3 and 4 (80 in week 3, 60 in week 4)
3. 160 books total for weeks 5, 6, and 7 (60 in week 5, 40 in week 6, 60 in week 7)
4. 40 fewer books were sold in week 8 than week 7 (week 8 had 20, week 7 had 60)
5. 440 books total across all 8 weeks
6. 55 books per week on average
