Answer:
The initial fee for the ticket is 3.5 dollars
Step-by-step explanation:
For 4 stops, the price of a ticket is 8 dollars
For 8 stops, the price of a ticket is 14 dollars.
- The number of stops increased in this case is: 8 -4 = 4 stops
When there are more 4 stops, the price of a ticket also increase from 8 to 14 dollars => the increase in price is: 14 - 8 = 6 dollars.
Similarly, for 8 stops, the price of a ticket is 14 dollars.
For 12 stops, the price of a ticket is 20 dollars.
- The number of stops increased in this case is: 12 - 8 = 4 stops
When there are more 4 stops, the price of a ticket also increase from 14 to 20 dollars => the increase in price is: 20 - 14 = 6 dollars.
So that, the price for an extra stop is constant and equal to: 6/4 = 1.5 dollars
=> The price for 3 extra stops is: 1.5 x 3 = 4.5 dollars
For 4 stops, the price of a ticket is 8 dollars
=> The initial fee for the ticket = 8 dollars - The price for 3 extra stops = 8 - 4.5 = 3.5 dollars.
