Verified step by step guidance
1
Identify the total number of respondents, which is given as 1182.
Identify the number of respondents who said that driving is a chore, which is given as 331.
To find the percentage, use the formula: \( \text{Percentage} = \left( \frac{\text{Number of respondents who said driving is a chore}}{\text{Total number of respondents}} \right) \times 100 \).
Substitute the given values into the formula: \( \text{Percentage} = \left( \frac{331}{1182} \right) \times 100 \).
Calculate the division and then multiply by 100 to find the percentage of respondents who said that driving is a chore.
