Question

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?

Answer 1

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.
