The director's goal is ticket sales of at least $4500. So, the inequality representing the director's goal is:
7.5a + 5s ≥ 4500
The correct option is:
D) 7.5a + 5s ≥ 4500
Let, set up the inequality based on the given information.
Let "a" represent the number of adult tickets sold and "s" represent the number of student tickets sold.
The revenue from adult tickets is given by: 7.5a (as each adult ticket costs $7.50)
The revenue from student tickets is given by: 5s (as each student ticket costs $5.00)
To find the total ticket sales, we add the revenue from adult and student tickets:
Total ticket sales = 7.5a + 5s
Now, the director's goal is ticket sales of at least $4500. So, the inequality representing the director's goal is:
7.5a + 5s ≥ 4500
The correct option is:
D) 7.5a + 5s ≥ 4500
