Question

Taxi fare from an airport to a nearby town is $0.80 per mile driven, plus $2 for tolls. Let y represent the lare and r the miles driven on one trip. write the equation for y in terms of r. Find the fare when the distance driven is 17 miles.

Answer 1

How many tolls have to be paid? Assuming one toll:

y = $2 + .80r

Substitute 17 for r and solve.
