To participate in a competition, a person's age must not be less than 16 years. If the person's age is \(a\) years, which inequality is correct?

Answer and explanation

Correct answer: \(a\ge 16\)

“Not less than 16 years” means “at least 16 years,” so the age may be equal to 16 or greater: \(a\ge 16\). Option D is incorrect because \(a>16\) excludes the age of exactly 16 years. In an exam, translate “not less than” or “at least” as \(\ge\).
