Answer: Mikel travelled 6 miles.
Step-by-step explanation:
Let x represent the number of miles that Mike travelled.
Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of $6 plus $3 per mile. This means that if he traveled for x miles, the total cost, not including tip would be
3x + 6
The total fare was $24, not including the tip. This means that
3x + 6 = 24
3x = 24 - 6
3x = 18
x = 18/3
x = 6
