# Inequalities In Signs

### By Will Kramer

## 1.

## What Is the Inequality?

a= Age

a ≥ 4

This is because the sign says children 0-3 cannot use the toy. This means children that are 3 or under the age of 3 cannot use it.

## 2.

## 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.

## 3.

## What Is The Inequality?

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.

## 4.

## What Is The Inequality?

e= Elephant's Weight

c= Cars' Weight

e ≠ c

This is because on the scale, the elephant is weighing down the cars.
