To find the percentage of residents who thought the city should devote more funds to repair roads, you can use the following formula:
\[ \text{Percentage} = \left( \frac{\text{Number of residents who support more funding}}{\text{Total number of residents surveyed}} \right) \times 100 \]
Plugging in the numbers:
\[ \text{Percentage} = \left( \frac{865}{2330} \right) \times 100 \]
Calculating this:
\[ \text{Percentage} \approx 0.3712 \times 100 \approx 37.12% \]
Rounding to the nearest percent, the estimate is:
\[ \boxed{37} , % \]
