On four consecutive​ days, a concert pianist practiced for 3 1/2 ​hours,
6 1/3​hours,
4 1/4 ​hours, and
5 1/6hours. Find the​ pianist's total practice time.

19 hours and 15 minutes

Step-by-step explanation:

if you add it up all together it equals to 19.25 hours but you would convert it into 19 hours and 15 minutes

(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).
