Answer:
Explanation:
To find the percent of the people who attended the Baybridge Middle School Winter Formal who are not students at Baybridge, we can use the following steps:
Find the fraction of non-student attendees: 18 attendees out of 90 total attendees can be represented as 18/90.
Convert the fraction to a decimal: 18/90 = 0.20, which can be rounded to 0.2.
Convert the decimal to a percentage: 0.2 * 100 = 20%.
So, 20% of the people who attended the Baybridge Middle School Winter Formal are not students at Baybridge.
