1. **State the problem:** Calculate the refund rate given the total refund amount and the total sales amount (which is not provided, so we assume it or explain the formula). 2. **Identify the data:** The total refund amount is $2234$. 3. **Explain the refund rate formula:** Refund rate is typically calculated as $$\text{Refund Rate} = \frac{\text{Total Refund Amount}}{\text{Total Sales Amount}} \times 100\%$$ 4. **Note:** Since the total sales amount is not provided, we cannot compute the exact refund rate. If you provide the total sales amount, we can calculate it. 5. **Example:** If total sales were $10000$, then $$\text{Refund Rate} = \frac{2234}{10000} \times 100\% = 22.34\%$$ 6. **Conclusion:** Please provide the total sales amount to calculate the refund rate accurately.
