On Christmas Day 2009, there was a bomb scare aboard a Detroit-bound plane. Soon afterwards, a poll indicated that 42% of Americans were worried that they or a close friend or family member would become a victim of terrorism. The poll had a 5% margin of error. Create an absolute value inequality that describes the ranges of possible poll percentages and rewrite it as an inequality.

5% of 42 = 2.1
So, 45-2.1 <= x <= 45+2.1
