The problem presented in the image asks to write an equation for how many more boxes of hand sanitizer Mrs. Hong needs to buy. Here's the breakdown:

- **Mrs. Hong already has** 10 bottles of hand sanitizer.
- **She needs a total of** 510 bottles.
- **Hand sanitizer is sold in boxes of 25 bottles each**.

Let \( x \) represent the number of boxes Mrs. Hong needs to buy. Each box contains 25 bottles, so the total number of bottles from \( x \) boxes would be \( 25x \).

Since she already has 10 bottles, the equation for the total number of bottles needed is:

\[
25x + 10 = 510
\]

Now, looking at the answer choices:

1. \( 10x + 25 = 510 \)
2. \( 25 - 10x = 510 \)
3. \( 25x + 10 = 510 \)
4. \( 10 + 25x = 510 \)

The correct answer is **Option 3: \( 25x + 10 = 510 \)**, as this matches the correct equation format.

Would you like more details or have any questions?

Here are 5 related questions to deepen understanding:
1. How do you solve the equation \( 25x + 10 = 510 \) to find the value of \( x \)?
2. If the boxes contained 30 bottles each, how would the equation change?
3. What if Mrs. Hong only had 5 bottles instead of 10—how would you adjust the equation?
4. How many bottles would Mrs. Hong still need after purchasing 5 boxes?
5. How would you check if your solution to the equation is correct?

**Tip:** Always carefully define the variable and ensure the equation represents the real-world scenario described.

Mrs. Hong is buying bottles of hand sanitizer for her employees. She already has 10 bottles in her office and needs a total of 510 bottles. They are sold in boxes of 25. Write an equation to show how many more boxes of hand sanitizer she needs.

Learn how to write an equation to determine how many more boxes of hand sanitizer Mrs. Hong needs to buy. She already has 10 bottles and requires a total of 510 bottles, with each box containing 25 bottles. This problem covers basic linear equations suitable for students in Grades 6-8.
