Let’s go step by step to answer each question using the line graph.
---
1) How many cars were sold during May?
Look at the point for
May on the x-axis. Follow it up to the blue line, then look across to the y-axis (Cars sold). The point is at
20.
✔ Answer:
20

2) How many cars were sold in the first 3 months of the year?
First 3 months = January, February, March.
- Jan: 15
- Feb: 20
- Mar: 24
Add them:
15 + 20 = 35
35 + 24 =
59
✔ Answer:
59

3) How many more cars were sold in July than May?
July sales: Look at July → 26
May sales: We already found → 20
Difference: 26 - 20 =
6
✔ Answer:
6

4) Which month had 26 car sales?
Find 26 on the y-axis. Move right until you hit the blue line. That happens at
July.
✔ Answer:
July

5) True, False, or Can’t Tell?
We’ll check each statement one by one.
---
a) The beginning and end of the year had the lowest number of car sales.
Beginning = Jan (15), End = Dec (16) — both are low. But let’s see if any other month is lower? No — all others are 18 or higher. So yes, Jan and Dec are the two lowest.
✔ True
---
b) Car sales increased steadily from March to August.
“Steadily” means going up every single month without dropping.
Check:
- Mar: 24
- Apr: 22 ← went DOWN!
So not steady increase.
✔ False
---
c) August had twice as many sales as December.
August: 32
December: 16
Is 32 = 2 × 16? Yes!
✔ True
---
d) Salamander Autos made the most money in August and September.
The graph shows
number of cars sold, NOT how much money they made. Maybe some cars cost more than others? We don’t know prices. So we can’t tell about money.
✔ Can’t tell
---
e) Car sales decreased from August to December.
Check each month after August:
- Aug: 32
- Sep: 28 ↓
- Oct: 21 ↓
- Nov: 18 ↓
- Dec: 16 ↓
Yes — every month after August, sales went down.
✔ True
---
Final Answer:
1) 20
2) 59
3) 6
4) July
5) a) True, b) False, c) True, d) Can’t tell, e) True
