To represent the situation where Trevon practices his clarinet for at least 1 hour each day using the variable \( t \) for time (in hours), we can express this as an inequality.
Since "at least 1 hour" means that the time practiced should be greater than or equal to 1 hour, we can write the inequality as:
\[ t \geq 1 \]
This inequality states that the practice time \( t \) must be 1 hour or more.
