Answer:
27 %
Step-by-step explanation:
Given that Sheila predicts that 480 people will attendthe fall concert and There was an actual total of 350 people who attended the fall concert.
We know that
Percent error = [tex]\frac{people present-predicted people}{predicted people}\times100[/tex]
Percent error = [tex]\frac{480-350}{480}\times100[/tex]
Percent error = 27 %
