Problem Statement:
Straight Arrow Dress Shirts sold a lot of dress shirts last month. Each shirt has:
- 7 buttons down the front.
- 1 button on each sleeve (2 sleeves total, so 2 buttons).
They used
72,000 buttons in total on the shirts sold last month. The task is to determine how many shirts they sold.
---
Solution Approach:
1.
Determine the total number of buttons per shirt:
- Each shirt has:
- 7 buttons down the front.
- 1 button on each sleeve (2 sleeves), so \( 1 \times 2 = 2 \) buttons.
- Total buttons per shirt = \( 7 + 2 = 9 \) buttons.
2.
Set up the equation:
- Let \( x \) be the number of shirts sold.
- Since each shirt uses 9 buttons, the total number of buttons used is \( 9x \).
- We are given that the total number of buttons used is 72,000.
- Therefore, the equation is:
\[
9x = 72,000
\]
3.
Solve for \( x \):
- Divide both sides of the equation by 9:
\[
x = \frac{72,000}{9}
\]
- Perform the division:
\[
x = 8,000
\]
4.
Conclusion:
- The number of shirts sold is \( x = 8,000 \).

Final Answer:
\[
\boxed{8000}
\]
