Answer:
660 balloons and 14 packages
Step-by-step explanation:
first let's find out how many balloons we'll need for all the rooms together.
220x3=660
Now let's see how many packs of balloons we need.
660/50=13.2, since it isn't a whole number you'll need 14 packs and some will be left over.
I hope I can help and this isn't confusing!
