Answer:
247 blown up balloon left
Step-by-step explanation:
5 bags of round balloon with 24 balloon in each bag =
= 5 x 24 = 120 round balloons
3 bags of long balloon with 36 balloon in each bag =
= 3 x 36 = 108 long balloons
Part 1 Answer
120 round balloons - 108 long balloon = 12 balloons
therefore the clown bought 12 more round balloon than long balloon
Part 2
3 bags of heart-shaped balloons with 14 balloons in each bag =
= 3 x 14= 42 heart-shaped balloons
All the balloons were blown which equals
120 round balloons + 108 long balloons + 42 heart-shaped balloons =
= 270 balloons
23 balloons out of the 270 balloons burst which equals
270 blown balloon - 23 burst balloon = 247 blown-up balloons left
so,
247 blown-up balloons were left
