Central High School (CHS) is hosting a fundraising event.

• The venue, decorations, and disc jockey cost $1,400.

• The venue can hold at most 300 students.

• Tickets cost $20 for a CHS student and $30 for a non-CHS student.

Let s represent the number of CHS student tickets sold, and let n represent the number of non-CHS student tickets sold. If the school wants to earn money on this event, which system of inequalities represents the numbers of tickets that should be sold?

• 20s + 30n > 1,400

  s + n ≤ 300

• 20s + 30n > 1,400

  s + n < 300

• 20s + 30n > 300

  s + n ≤ 1,400

• 20n + 30s > 1,400

  s + n ≤ 300
