Answer:
Step-by-step explanation:
The admission fee into the state ride is $8 and each ride cost additional four dollars.
Let x represent the number of rides that Karen takes at the state fair.
Let y represent the total cost of x rides
Therefore, if Karen takes x ride at the state fair, the total cost of x ride would be
y = 4x + 8
Karen only has $30.00. Therefore, the number of rides that Karen can go on will be
30 = 4x + 8
4x = 30 - 8 = 22
x = 22/4 = 5.5
Karen can only go on 5 rides. She will get a balance of $2
