a We are given that the Low-Elevation Forest is above 1700 feet to 2500 feet. Letting e represent the elevation, it follows that e is greater than 1700 and less than or equal to 2500.
e>1700 and e≤ 2500
b
We are given that the Subalpine region covers from above 4000 feet to 6500 feet, while the Alpine region covers from 6500 to the peak at 14 410 feet. Together, we can see that these regions cover from above 4000 feet to 14 410 feet.
If we let e represent the elevation, it follows that e is greater than 4000 and less than or equal to 14 410.
e>4000 and e≤ 14 410
