Answer:
5x + 8y ≥ 1200
x + 2y ≤ 500
Step-by-step explanation:
Let x = number of $5 tickets
Let y = number of $8 tickets
Worth of ticket that must be sold = at least $1200
No more than 500 students can fit in the gym
Ticket worth equation :
Cost * number of tickets ≥ 1200
5x + 8y ≥ 1200
Number of students :
Person = 1
Couple = 2
x + 2(y) ≤ 500
x + 2y ≤ 500
