Answer:
Explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of children tickets that were sold.
The auditorium can hold no more than 200 audience members. This means that
x + y ≤ 200
An adult ticket costs $9 and a child's ticket costs $4. The students would like ticket sales of at least $1300. This means that
9x + 4y ≥ 1300
These are the set of inequalities that represents the situation.
