A popular restaurant determines that during the previous month, the average waiting time for its customers to be seated between 6 P.M. and 10 P.M. was 32 minutes. Its records show that for 85% of its customers, the waiting time to be seated did not vary more than 5.5 minutes from this average. Write and solve an absolute value inequality to describe the waiting time for the remaining 15% of customers during the same time period and graph the solution on a number line.
