Question

In one U.S city the taxi cost is $4 plus $0.70 per mile. If you are traveling from the airport there is an additional charge of $6.00 for tolls. How far can you travel from the airport by taxi for $27.50?

Answer 1

I think the answer is 25 miles.
6+4+.7x= 27.50
10+.70x= 27.50
.70x= 17.50
Divide both sides by .7 and the answer is 25.
