Math worksheet for students to practice interpreting line graphs using daily roll sales data.

Explanation:
Let’s solve each question step by step using the data given:

The daily roll sales are:
- Monday: 84 rolls
- Tuesday: 72 rolls
- Wednesday: 66 rolls
- Thursday: 48 rolls
- Friday: 54 rolls

Question 1: How many rolls were sold on Monday and Tuesday?
Add Monday + Tuesday:
84 + 72 = 156

Question 2: How many more rolls were sold on Wednesday than Thursday?
Subtract Thursday from Wednesday:
66 − 48 = 18

Question 3: How many dozen rolls were sold on Monday and Thursday?
First, find total rolls:
Monday = 84, Thursday = 48 → 84 + 48 = 132 rolls
Since 1 dozen = 12 rolls, divide by 12:
132 ÷ 12 = 11 dozen

Question 4: How many dozen rolls were sold in all?
Add all rolls:
84 + 72 + 66 + 48 + 54
Let’s compute step by step:
84 + 72 = 156
156 + 66 = 222
222 + 48 = 270
270 + 54 = 324 rolls
Now convert to dozens:
324 ÷ 12 = 27 dozen

Question 5: How many dozen rolls were sold on Friday?
Friday = 54 rolls
54 ÷ 12 = 4.5 → that’s 4 and 6/12 = 4½ dozen
So answer is: a. 4½ (since 4½ = 4.5)

Question 6: How many rolls were sold on Wednesday?
Wednesday = 66 rolls
Convert to dozen:
66 ÷ 12 = 5 remainder 6 → 5 and 6/12 = 5½ dozen
So answer is: a. 5 dozen? Wait — check options:
a. 5 dozen → 60 rolls
b. 5½ dozen → 5.5 × 12 = 66 rolls ✔
c. 6 dozen → 72 rolls
So correct is b. 5½ dozen

Now double-check all calculations:

1. 84 + 72 = 156 ✔
2. 66 − 48 = 18 ✔
3. 84 + 48 = 132; 132 ÷ 12 = 11 ✔
4. Total = 324; 324 ÷ 12 = 27 ✔
5. 54 ÷ 12 = 4.5 = 4½ ✔ → a
6. 66 ÷ 12 = 5.5 = 5½ ✔ → b

All correct.

Final Answer:
1. 156
2. 18
3. 11
4. 27
5. a
6. b
