Let’s solve this step by step.
---
Step 1: Understand the button count per shirt
Each dress shirt has:
-
7 buttons down the front
-
1 button on each sleeve
Since a shirt has
2 sleeves, that’s:
> 1 button × 2 sleeves =
2 sleeve buttons
So, total buttons per shirt =
> 7 (front) + 2 (sleeves) =
9 buttons per shirt

Step 2: Total buttons used last month
They used
72,000 buttons in total.
---
Step 3: Find number of shirts sold
If each shirt uses 9 buttons, then:
> Number of shirts = Total buttons ÷ Buttons per shirt
> = 72,000 ÷ 9
> =
8,000
---
✔ Final Answer: They sold 8,000 shirts.

💡 Explanation Recap:
- Each shirt needs 9 buttons (7 front + 1 per sleeve × 2).
- Total buttons used: 72,000.
- Divide total buttons by buttons per shirt → 72,000 ÷ 9 = 8,000 shirts.
This is a straightforward division problem once you calculate the total buttons per unit (shirt).
