To find the cost per mile, we need to divide the total cost by the number of miles driven.

$\text{Cost per mile} = \frac{\text{Total Cost}}{\text{Miles Driven}}$

Given:

• Total cost = $2475
• Miles driven = 15,000 miles

Substituting the values:

$\text{Cost per mile} = \frac{2475}{15000} = 0.165 \text{ dollars per mile}$

So, the cost per mile is $0.165.

Tip: When dealing with rates (like cost per mile), dividing the total amount by the number of units (miles, hours, etc.) will give you the rate per unit.
