People with a drivers license are at least 16 years old and no older than 85 years old

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:

1. The phrase at least means greater than or equal to. So we use the >= sign. 16 <= p
2. 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
