1. The problem states that the temperature $t$ in a freezer must be at most $-10$ degrees Fahrenheit. 2. "At most" means the temperature can be less than or equal to $-10$. 3. The inequality to represent this is: $$t \leq -10$$ 4. This means $t$ can be any value less than or equal to $-10$. 5. So the correct inequality is $t \leq -10$. 6. This inequality correctly models the freezer temperature requirement.
