You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.

Let = the number of miles traveled and = the total cost for the trip.

If a trip is 8 miles, which company would be the better choice?
