Description: Let's tackle this word problem together. We'll interpret the information and then construct a linear inequality to solve it. Created by Sal Khan and Monterey Institute for Technology and Education. So if we simplify this left-hand side, we get the number of people in Las Vegas 78,000 is going to be greater than or equal to 120,000. And we're just left with the number of people who attended the show in Las Vegas is going to be greater than or equal to 120,000 minus 78,000. So the number of people who attended Las Vegas is going to be greater than or equal to 42,000 people.
