Example4.5.25

Uber is a ride-sharing company. Its pricing in Portland factors in how much time and how many miles a trip takes. But if you assume that rides average out at a speed of 30 mph, then their pricing scheme boils down to a base of \(\$7.35\) for the trip, plus \(\$3.85\) per mile. Use a slope-intercept equation and algebra to answer these questions.

  1. How much is the fare if a trip is \(5.3\) miles long?

  2. With \(\$100\) available to you, how long a trip can you afford?
