To find the average cost per mile, you can use the following formula:
\[ \text{Average cost per mile} = \frac{\text{Total car expenses}}{\text{Total miles driven}} \]
Given:
- Total car expenses = $625
- Total miles driven = 9,600 miles
Substituting the values into the formula:
\[ \text{Average cost per mile} = \frac{625}{9600} \approx 0.06510417 \]
Now, rounding this result to the nearest hundredth:
\[ \text{Average cost per mile} \approx 0.07 \]
Therefore, the average cost per mile is $0.07.
