An absolute value inequality that models this situation: 
The required compound inequality representing all possible weights for Mr. Bean.: 
<u>Given:</u> For the last 20 years,
Mr. Bean has weighed 120 pounds, give or take 4 pounds.
<u>To write</u>: a) An absolute value inequality that models this situation.
b) a compound inequality representing all possible weights for Mr. Bean.
<u>Computation:</u>
Let <em>x</em> be the actual weight of Mr. Bean,
then
Required absolute inequality:
It can be written as

Add 120 on all sides , we get
