Question

"within" meaning anything 12 or lower because if our maximum is 34 and they could hold it for 12 seconds, they cant hold it longer than 12..

So if 12, in this case, is the highest they can go, what do you think..?

Use x as the possible number of seconds students can hold their breath. $$12-x \le34$$ I think.. I'm not too sure because if the most they've held it has been 12, they can hold it for anything less than 12. So it can be.. $$x \le12$$
