Hello there! I can help you! So the centerpieces take 15 minutes to make, and x equals the amount of centerpieces. That part makes 15x. Just by looking at the answers, A and C are already eliminated. We are adding up the time. the florst has already spent 2 hours, which equals 120 minutes. She will spend no more than 6 hours or 360 minutes on creating the centerpieces. We add the time, not subtract. B is the only one that shows that. 120 + 15x ≤ 360. The answer is B. Your answer is correct.
