Answer:
$2
Step-by-step explanation:
Intial fee is x. Number of stops is y. You can set up these equations.
- x+4y=8
- x+8y=14
- 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.
- x+6=8
- Subract 6, x=2
