An outdoor swimming pool costs $8 per day to visit during the summer. There is also a $25 yearly registration fee. Is the total cost proportional to the total number of days visited?

No
Explanation:
The equation of cost includes the flat fee. This fees makes it so the cost is not proportional to the number of days visited.
To be proportional you'd have to have no flat fee:
1 day = $8
2 days = $16
5 days = $40
10 days = $80, etc.
