7-59.

If each mile costs $3, 2 miles would cost$11.
$6 plus the flat fee of$5.
How much would 8 miles cost?

2 miles : $11 8 miles:$29

If we let a variable represent the miles traveled, we can create an expression to represent the cost for her transportation.

Since each mile costs $3, this can be represented as$3(x).
Because she had to also pay a flat fee, this can be represented as a constant, $5.$3(x) + $5$3(x) + $5 =$23
How many miles did she travel?
