What Is the Inequality?
a= Age
a ≥ 4

What Is The Inequality?
w= Total Weight
w < 25,000
This is because 25,000 lbs is the capacity for the elevator. It cannot equal or go over its capacity. Therefore, it must be less than 25,000 lbs.

p= People
p ≤ 350
This is because 350 is the MAXIMUM. This means there can be less than or equal to 350 people, but it cannot exceed that.
