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.
