Why do you think the cart rolls farther when it starts from a higher position?

It has higher PE which can be converted into kinetic energy. The car also has had more work done on it when its at a higher position.

Step-by-step explanation:

This is because the cart gains speed as it goes from the top of higher point to bottom.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
