Answer: you can travel 25 miles from the airport by taxi for $23.00
Explanation:
Let x represent the number of miles that you travel from the airport by taxi.
In one U.S. city, the taxi cost is $3 plus $0.60 per mile. If you are traveling from the airport, there is an additional charge of $5.00 for tolls. This means that if you travel x miles from the airport by taxi, the total amount that you would pay is expressed as
3 + 0.6x + 5
= 0.6x + 8
Therefore, if you travel from the airport by taxi for $23.00, it means that
0.6x + 8 = 23
0.6x = 23 - 8
0.6x = 15
x = 15/0.6
x = 25
