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? (1 point) Responses x+y<400 and 30x+50y≥14,000 x+y<400 and 30x+50y≥14,000 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≤14000

The correct linear systems model for the sale of concert tickets is:

x + y < 400 (equation 1)
30x + 50y ≥ 14,000 (equation 2)

So, the correct answer is x + y < 400 and 30x + 50y ≥ 14,000.
