At this point of the Earth's surface, the Stratosphere layer is at most at 50 km, and at least at 16 km altitude.
If y represents a height which is in the Stratosphere layer, then we know that y is at least 16 km, which is represented by [tex]16 \leq y[/tex],
and y is at most 50 km, which is represented by [tex]y \leq 50[/tex].
Combining these 2 inequalities we have:
[tex]16 \leq y \leq 50[/tex], where y is in km
