Answer:
w ≥ 66
Step-by-step explanation:
You know that anything less than 66 would not cause any effect, so you need something that is exactly 66 or more than 66 for the airbag to deploy.
Thus, w ≥ 66
≥ means that w is more than or equal to 66. (66 and above)
< means that w is less than 66. (65 and below)
> means that w is more than 66. (67 and above)
≤ means that w is less than or equal to 66. (66 and below)
