Final answer:
The equation or inequality that represents the situation is 17 ≥ 5 + 3t.
Step-by-step explanation:
To represent the situation where 17 is at least 5 more than 3 times, we can use the inequality symbol ≥ (greater than or equal to) since it is at least. So, the correct equation or inequality is 17 ≥ 5 + 3t (Option b).
