Line Graph Worksheet 4C Auto Sales: Analyze monthly car sales data from a line graph.

Let's solve each question step by step using the line graph provided in the worksheet.

---

Understanding the Graph:

- The x-axis shows months from January to December.
- The y-axis shows the number of cars sold, ranging from 10 to 34.
- Each point on the graph represents the number of cars sold in a given month.

We’ll read values directly from the graph:

| Month | Cars Sold |
|-------|-----------|
| Jan | 15 |
| Feb | 20 |
| Mar | 24 |
| Apr | 22 |
| May | 20 |
| Jun | 23 |
| Jul | 26 |
| Aug | 32 |
| Sep | 28 |
| Oct | 21 |
| Nov | 18 |
| Dec | 16 |

Now, answer the questions:

#### 1) How many cars were sold during May?

From the graph, May = 20 cars.

✔ Answer: 20

---

#### 2) How many cars were sold in the first 3 months of the year?

Add January + February + March:

- Jan: 15
- Feb: 20
- Mar: 24

Total = 15 + 20 + 24 = 59

✔ Answer: 59

---

#### 3) How many more cars were sold in July than May?

- July: 26
- May: 20

Difference = 26 - 20 = 6

✔ Answer: 6

---

#### 4) Which month had 26 car sales?

Look at the graph: July has 26 cars sold.

✔ Answer: July

#### 5) Answer true, false, or can’t tell:

##### a) The beginning and end of the year had the lowest number of car sales.

- Beginning (Jan): 15
- End (Dec): 16
- Other low points: May (20), Nov (18), etc.
- But Jan (15) is the lowest, Dec (16) is second-lowest.
- However, Oct (21), Nov (18), and Dec (16) are all higher than Jan.
- So yes, both Jan and Dec are among the lowest.

But note: Jan is the lowest, and Dec is not the lowest, but still quite low.

But the statement says "the beginning and end" — meaning Jan and Dec — both had low numbers, and indeed, they were the two lowest?

Wait: Let’s check:
- Jan: 15 ✔ lowest
- Dec: 16 ✘ not the lowest, but close
- Is there any month with fewer than 15? No.
- So Jan is the lowest, Dec is second-lowest.

So both beginning and end had among the lowest.

But the statement says “had the lowest number” — singular. That could be interpreted as both had the lowest, which isn't accurate because Jan was lower than Dec.

But actually, it says "the lowest number" — possibly implying they were tied for lowest? They're not.

So technically, only January had the lowest, not both.

Therefore, this statement is false.

✘ Answer: False

> Reason: Only January had the lowest sales (15). December had 16, which is higher. So both didn't have the lowest.

##### b) Car sales increased steadily from March to August.

Check the trend:

- Mar: 24
- Apr: 22 → decrease
- May: 20 → decrease
- Jun: 23 → increase
- Jul: 26 → increase
- Aug: 32 → increase

So: March → April → May decreased → not steady increase

✘ Answer: False

> Because sales dropped in April and May.

---

##### c) August had twice as many sales as December.

- Aug: 32
- Dec: 16

Is 32 = 2 × 16? Yes! 2 × 16 = 32

✔ Answer: True

---

##### d) Salamander Autos made the most money in August and September.

This is tricky.

We know car sales were highest in August (32) and September (28) — so more cars sold.

But the statement talks about money made, not number of cars.

We don’t know:
- Price per car
- Whether all cars were sold at same price
- Any discounts or variations

So we can’t determine if they made more money just from car count.

For example, maybe they sold expensive cars in other months.

So we can’t tell.

✘ Answer: Can’t tell

---

##### e) Car sales decreased from August to December.

Check the data:

- Aug: 32
- Sep: 28 → ↓
- Oct: 21 → ↓
- Nov: 18 → ↓
- Dec: 16 → ↓

Yes, every month from August to December shows a decrease.

✔ Answer: True

---

✔ Final Answers:

1) 20
2) 59
3) 6
4) July
5)
a) False
b) False
c) True
d) Can’t tell
e) True
