A Taylor Swift concert is selling tickets. Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Fewer than 400 tickets in total were sold. Lawn tickets cost $30 each and seat tickets cost $50 each. The organizers want to make at least $14,000 from ticket sales.
Which of the following linear systems models the sale of concert tickets?

Responses
x+y>400 and 30x+50y≥14000
x+y>400 and 30x+50y≥14000
x+y<400 and 30x+50y≤14000
x+y<400 and 30x+50y≤14000
x+y<400 and 30x+50y≥14,000
The correct linear systems model for the sale of concert tickets is:
x + y < 400 (to represent that fewer than 400 tickets were sold)
30x + 50y ≥ 14,000 (to represent that the organizers want to make at least $14,000 from ticket sales)
Therefore, the correct option is:
x + y < 400 and 30x + 50y ≥ 14,000
