• A. 1
• B. $1(\frac{1}{4})$
• C. $1(\frac{3}{4})$
• D. 2

Answer 1

Answer: (B)

$1(\frac{1}{4})$

Answer 2

The correct option is (B): $1(\frac{1}{4})$
Explanation: To find out how many boxes of light bulbs the worker used, we first calculate the total number of bulbs replaced:
1. Total bulbs replaced:
- In the shipping department: 17 bulbs
- In the accounting department: 13 bulbs
$\text{Total bulbs replaced} = 17 + 13 = 30 \text{ bulbs}$
2. Bulbs per box:
- Each box contains 24 bulbs.
3. Number of boxes used:
To find the number of boxes, we divide the total bulbs replaced by the number of bulbs per box:
$\text{Number of boxes} = \frac{30}{24} = 1.25$
This can be expressed as:
$1 \frac{1}{4} \text{ boxes}$
Thus, the worker used $1(\frac{1}{4})$ boxes of bulbs, making the correct answer Option B: $1(\frac{1}{4})$.
