1. **State the problem:** We need to verify the calculations of the Refund Rate and Aftersale Rate based on the given totals. 2. **Given data:** - Total Refund Amount = 24972 - Total NMV = 167708 3. **Formulas:** - Refund Rate = \frac{\text{Total Refund Amount}}{\text{Total NMV}} - Aftersale Rate = \frac{\text{Total Refund Amount}}{\text{Total Refund Amount} + \text{Total NMV}} 4. **Calculate Refund Rate:** $$\text{Refund Rate} = \frac{24972}{167708} \approx 0.1488 = 14.88\%$$ 5. **Calculate Aftersale Rate:** $$\text{Aftersale Rate} = \frac{24972}{24972 + 167708} = \frac{24972}{192680} \approx 0.1296 = 12.96\%$$ 6. **Interpretation:** - Refund Rate is approximately 14.9%, which matches the given value. - Aftersale Rate is approximately 13.0%, which also matches the given value. **Final answer:** The calculations are correct.
