Piper receives 6 gumballs for every 30 minutes of piano she plays. If she wants 22 gumballs, how many minutes does she need to play?

110 minutes

Step-by-step explanation:

To find this we first find out how much Piper has to play to get one gumball. So what we do is divide 30(minutes) by 6 (gumballs), which gets us 5. This tells us that she has to play 5 minutes to get 1 gumball. Now if she wants 22 gumballs, we reverse... So we times 22 by 5, which gets us our answer of 110.

Hope this helps!
