Example 6-6a

Housing According to a recent survey, the average monthly rent for a one-bedroom apartment in one city is $750. However, the actual rent for any given one-bedroom apartment might vary as much as $250 from the average.

Write an absolute value inequality to describe this situation.

Slide 104

Example 6-6b

Rewrite the absolute value inequality as a compound inequality. Then solve for r.

Slide 105

Health The average birth weight of a newborn baby is 7 pounds. However, this weight can vary by as much as 4.5 pounds.

a. Write an absolute value inequality to describe this situation.

b. Solve the inequality to find the range of birth weights for newborn babies.
