Answer:

$2

Explanation:

Intial fee is x. Number of stops is y. You can set up these equations.

  1. x+4y=8
  2. x+8y=14
  3. x+12y=20

You can subtract one from the other:

x+8y=14

- x+4y=8

–––––––

4y=6

We now know that 4y=6. The first equation had 4y, so we can put 6 instead of 4y.

  1. x+6=8
  2. Subract 6, x=2
