Answer:
15 Hope this helps :)
Step-by-step explanation:
each bag has 15 balloons
21 balloon left divide that
by 3 bag cause that is the number of bags you have
So that leaves ya with 7 balloons in each bag
you already took out 8 balloons from each bag
SO ADD 8+7 .... and you get 15
The number of balls that were initially in the bag is 15
Javler bought 3 bags of balloons
He used 8 balloons from each bag
There were 21 balloons left over in the bag
= 21/3
= 7
= 7 + 8
= 15 ballons
Hence there are 15 balloons originally in the bag
