Pretty please answer this question I really bad at math

The answer is 19, each whole shaded columns are tens, and the mini shaded blocks are ones, add it together and you get 19.

Step-by-step explanation:

(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
