Show Answer Key & Explanations Step-by-step solution for: Interpreting Line Plots worksheet
Let’s go step by step through each question using the line plot. Remember: each “x” = 1 box sold.

We’ll count the x’s above each day number to find how many boxes were sold that day.

Here’s what we see from the plot (counting x’s per day):

- Day 1: 4 x’s → 4 boxes
- Day 2: 3 x’s → 3 boxes
- Day 3: 6 x’s → 6 boxes
- Day 4: 5 x’s → 5 boxes
- Day 5: 1 x → 1 box
- Day 6: 9 x’s → 9 boxes
- Day 7: 8 x’s → 8 boxes
- Day 8: 7 x’s → 7 boxes
- Day 9: 5 x’s → 5 boxes
- Day 10: 5 x’s → 5 boxes

Now let’s answer each question:

---

1) How many boxes did he sell on day 8?
→ Look at day 8: 7 x’s → 7 boxes

2) Did he sell more boxes on day 7 or day 2?
→ Day 7: 8 boxes, Day 2: 3 boxes → Day 7

3) Did he sell fewer boxes on day 9 or day 6?
→ Day 9: 5 boxes, Day 6: 9 boxes → Day 9

4) How many days did he sell more than 3 boxes?
More than 3 means 4 or more. Let’s check:

- Day 1: 4 → yes
- Day 2: 3 → no
- Day 3: 6 → yes
- Day 4: 5 → yes
- Day 5: 1 → no
- Day 6: 9 → yes
- Day 7: 8 → yes
- Day 8: 7 → yes
- Day 9: 5 → yes
- Day 10: 5 → yes

That’s Days 1, 3, 4, 6, 7, 8, 9, 10 → 8 days

5) How many days did he sell fewer than 7 boxes?
Fewer than 7 means 6 or less.

Check each day:

- Day 1: 4 → yes
- Day 2: 3 → yes
- Day 3: 6 → yes
- Day 4: 5 → yes
- Day 5: 1 → yes
- Day 6: 9 → no
- Day 7: 8 → no
- Day 8: 7 → no (not *fewer* than 7)
- Day 9: 5 → yes
- Day 10: 5 → yes

Days: 1, 2, 3, 4, 5, 9, 10 → 7 days

6) What is the combined amount of boxes he sold on day 3 and on day 10?
Day 3: 6, Day 10: 5 → 6 + 5 = 11

7) He sold the greatest number of boxes on which day?
Look for highest count: Day 6 has 9 → Day 6

8) He sold the least amount of chocolate on which day?
Lowest count: Day 5 has only 1 → Day 5

9) Which days (if any) did he sell more than 8 boxes?
More than 8 means 9 or more. Only Day 6 has 9 → Day 6

10) What is the difference in the number of boxes he sold on day 7 and the number he sold on day 5?
Day 7: 8, Day 5: 1 → 8 - 1 = 7

11) Which day did he sell exactly 8 boxes?
Look for day with exactly 8 x’s → Day 7 → Day 7

---

Final Answer:
1) 7
2) Day 7
3) Day 9
4) 8
5) 7
6) 11
7) Day 6
8) Day 5
9) Day 6
10) 7
11) Day 7
