To find the percentage of residents who prefer to shop at Walmart, you can use the following formula:
\[ \text{Percentage} = \left( \frac{\text{Number of residents who prefer Walmart}}{\text{Total number of residents}} \right) \times 100 \]
Given:
- Number of residents who prefer Walmart = 9
- Total number of residents = 47
Now, plug the values into the formula:
\[ \text{Percentage} = \left( \frac{9}{47} \right) \times 100 \approx 19.15% \]
Therefore, approximately 19.15% of residents prefer to shop at Walmart.
