Which is greater 8 1/2 or 9 1/2 and how do you put it as a expression using > < and =

8 1/2 is less than 9 1/2, 8 1/2< 9 1/2

(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
