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

Answer:

You can travel from the airport by taxi for 34.50 about 14.4 miles.
