What is rounding? i don't know what it is

Rounding is making the value of a number to the closest whole number or multiple of ten.

Step-by-step explanation:

If you have 8.86, you could round that to 9, since the decimal is close.

Hope this helps!

(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).

hope i
