Question

Brianna hoped to get 100 pumpkins from her garden this year. Since the weather was really great, 20% more pumpkins grew than expected. Unfortunately, animals ate 30% of all the pumpkins that grew.
How many pumpkins were left?

Answer 1

Answer:

80 pumpkins are left

Step-by-step explanation:

If 20% of 100 is 20, then it's going to equal 120, so 30% is 40 if its 120.

Answer 2

9514 1404 393
