Question 118460: If possible, please show how to work this problem.
The state fair is coming to town. since you love the rides, you can't wait go go. When you get the ticket counter you notice three options for purchasing tickets.
option 1 pay one price at the gate for limitless riding,for $125
option 2 pay $5 at the gate and then paying $0.75 for each ride you go on.
option 3 pay nothing at the gate and pay $1.25 for each ride.
Write linear equations for each option that describe your cost (y) as a function of how many rides you gon on (x). If you knew ahead of time that you were going to experience 17 rides, which option would be cheapest?
Thank you

You can put this solution on YOUR website! option 1 pay one price at the gate for limitless riding,for $125
option 2 pay $5 at the gate and then paying $0.75 for each ride you go on.
option 3 pay nothing at the gate and pay $1.25 for each ride.

------------
Let "x" be number of rides.
------------
Option 1: cost = 125
Option 2: cost = 5 + 0.75x
Option 3: cost = 1.25x
---------------------
Cost for 17 rides:
Option 1: cost = 125
Option 2: cost = 5 + 0.75*17 = 17.75
Option 3: cost = 1.25*17 = 21.25
---------------------
Option 2 would be least expensive for 17 rides.
