Answer:
84 pumpkins; less than she expected
Step-by-step explanation:
Find 20% of 100 and add the percent to 100. That is 120.Then find 30% of 120, which is 36. Then do 100-36 to get 84 pumpkins. That is less than 100 so she got less than she hoped.
The final number of pumpkins less than she ​hoped is 84 pumpkins.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100.
A percentage is a dimensionless number, it has no unit of measurement.
Brianna hoped to get = 100 pumpkins
percentage of increased yield = 20%
∴ number of pumpkins = 100*20/100
                   = 20 pumpkins more.
   total pumpkins yield = 100 + 20 = 120.
percentage of pumpkins animals eat = 30%
     ∴ number of pumpkins = 120*30/100
                   = 36 pumpkins more.
total number of pumpkins she left = 120 - 36
                            = 84.  answer.
