People with a drivers license are at least 16 years old and no older than 85 years old. Set up the inequality, where p represents the people: The phrase at least means greater than or equal to. So we use the >= sign. 16 <= p The phrase no older than means less than or equal to. So we use the <= sign. p <= 85 Combine these inequalities, and we get: 16 <= p <= 85 To see the interval notation for this inequality and all possible values, visit the interval notation calculator.
