To determine the average cost of gasoline per mile, we need to follow several steps. Here is the solution step-by-step:
### Step 1: Determine the gasoline cost
1. Calculate the total spent on insurance, registration, and maintenance:
[tex]\[
\text{Total of other expenses} = \$972 + \$114 + \$105 = \$1191
\][/tex]
2. Subtract these expenses from the total operating cost to find out the cost of gasoline:
[tex]\[
\text{Gasoline cost} = \$1837 - \$1191 = \$646
\][/tex]
### Step 2: Determine the average cost per mile for gasoline
1. Given that Benito drove 7600 miles in total, we need to calculate the average cost per mile:
[tex]\[
\text{Average cost per mile} = \frac{\text{Gasoline cost}}{\text{Total miles driven}} = \frac{\$646}{7600 \text{ miles}} \approx \$0.085 \text{ per mile}
\][/tex]
### Step 3: Select the correct choice
The calculated average cost of gasoline per mile is approximately \[tex]$0.085, which corresponds to option D.
Thus, the correct answer is:
D. $[/tex]8.5 \text{C}$
