Question 743443
A popular band recently returned from a successful tour where they played to at least 140,000 people. The number of people attending each of the three concerts can be represented by the following expressions. 
Denver: 2x + 10,000; 
Seattle: 2(2x + 10,000); 
Las Vegas: 4x 
Which of the following could represent the minimum number of people that attended the concert in Las Vegas?
-----
Inequality:
2x+10,000 + 4x+20,000 + 4x >= 140,000
10x + 30,000 >= 140,000
10x > = 110,000
x >= 11000
---
Denver is >= 32000
Seattle is >= 64000
Las Vegas is >= 4x >= 44,000
