Step-by-step explanation:

Think about it as a t chart:

The numbers before the dot are your n values. If you plug in 1 for n, you get 3. If you plug in 2 for n, you get -6.

(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).
