In one us city the Taxi cost is $2 plus $0.90 per mile . If you are traveling from the airport, there is an additional charge of $3.50 for tolls. How far can you travel from the airport by taxi for $41.50?

Respuesta :

The answer is 40 miles.

First you have to put it into an equation. When you do this you get .90x+2+3.50=41.50

Now you have to solve using inverse operation. Subtract 3.50 from 41.50 and you get 38.00. Now your equation is .90x+2=38.00

Now you have to subtract 2 form 38.00 and you get 36.00. Now you get .90x=36.00

Then you have to divide 36.00 by .90 and you get 40. Therefore x=40, which means you can travel 40 miles.
