Question

Amy is building a house. the basement floor is at -15 feet. the roof of the house is above the ground 25 feet. write an inequality to compare the heights. explain the meaning of the inequality.
BONUS: what is an inequality.

Answer 1

An inequation is a mathematical expression that is used to make constraints given a problem.
 For example, this is a problem of heights.
 There is a minimum height and a maximum height.
 We can use the following inequation to describe the problem:
 Let
 x = height in feet.
 The inequation is:
 -15 <= x <= 25
 answer:
 -15 <= x <= 25
