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? can u use division please and please explain

8 days

Step-by-step 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.

cost =25+8d

To be proportional you'd have to have no flat fee: cost =8d

1 day = $8

2 days = $16

5 days = $40

10 days = $80, etc.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
