Answer:
187
Step-by-step explanation:
Total People: 321
Total People Younger than 10 years old: 134
Take the total people and subtract all people younger than 10 years old. All you have left is people who are NOT younger than 10 years old.
321(Total People) - 134(People younger than 10 years old) = 187 people NOT younger than 10 years old.
