Answer: 137.17 miles
Step-by-step explanation: To know the driven miles, we will have to find the extra money paid divided by the unitary price of each driven mile.
Extra money=$29.46-$25=$4.46
Miles=
=31.17 miles
However, this price per mile is only charged after 100 miles, therefore we will have to sum the extra miles driven and the 100 miles for the basis
Total=100 miles+31.17 miles=137.17
