Show Answer Key & Explanations Step-by-step solution for: Line graph/chart worksheets based on the Singapore math curriculum ...
Since I can't view or access images directly, I can't see the specific graph or details in the image you uploaded. However, based on your description, it seems like the task involves analyzing a line graph that shows the number of books sold each month over a year (January to December). The questions ask for:

1. How many books were sold in March?
2. How many books were sold in April?
3. How many books were sold in May?
4. How many books were sold in July?
5. What was the average number of books that were sold each month?

To solve this problem, I need to interpret the graph data. Since I don’t have the actual graph, I’ll walk you through the general steps to solve such problems and provide an example.

🔍 Step-by-Step Guide to Solving This Problem



#### 1. Understand the Graph
- The x-axis represents months (Jan to Dec).
- The y-axis represents the number of books sold.
- Each point on the graph corresponds to the number of books sold in a given month.
- You read the value by finding the height of the point above the month.

#### 2. Answering the Questions

Let’s assume the graph looks something like this (based on typical patterns):

| Month | Books Sold |
|---------|------------|
| Jan | 80 |
| Feb | 100 |
| Mar | 120 |
| Apr | 90 |
| May | 110 |
| Jun | 130 |
| Jul | 140 |
| Aug | 120 |
| Sep | 100 |
| Oct | 110 |
| Nov | 130 |
| Dec | 150 |

*(Note: These are hypothetical values. Replace them with actual values from your graph.)*

Now Let's Solve Using These Values:



#### 1. How many books were sold in March?
→ Look at March → 120 books

#### 2. How many books were sold in April?
→ Look at April → 90 books

#### 3. How many books were sold in May?
→ Look at May → 110 books

#### 4. How many books were sold in July?
→ Look at July → 140 books

#### 5. What was the average number of books sold each month?

Formula:
\[
\text{Average} = \frac{\text{Total books sold in all months}}{\text{Number of months}}
\]

Add up all monthly sales:
\[
80 + 100 + 120 + 90 + 110 + 130 + 140 + 120 + 100 + 110 + 130 + 150 = 1360
\]

Divide by 12 months:
\[
\frac{1360}{12} = 113.\overline{3} \approx 113.33
\]

So, the average is approximately 113.33 books per month.

📌 Final Answers (Based on Hypothetical Data):



1. March: 120 books
2. April: 90 books
3. May: 110 books
4. July: 140 books
5. Average: 113.33 books/month

❗Important Note:


Please replace these numbers with the actual values from your graph. To do that:

- Locate each month on the x-axis.
- Follow the point vertically to the y-axis to read the number of books sold.
- Use those real numbers to compute the average.

If you can describe the graph (e.g., "In March, the point is at 120", etc.), I can give you the exact answers!
