In one u. s city, the taxi cost is $2 plus 0.08 per mile. if you are traveling from the airport, there is and additional charge of $4.50 fir tolls. how far can yoh travel from the airport by taxi for 34.50?

First we define variables.
 x = number of miles.
 y = total cost in $
 We write the equation that adapts to the problem:
 y = 2.08x + 4.50
 For y = 34.50 we have:
 34.50 = 2.08x + 4.50
 We clear x:
 x = (34.50-4.50) / (2.08)
 x = 14.4 miles
  
 You can travel from the airport by taxi for 34.50 about 14.4 miles.
