Final answer:
The correct system of equations that can be used to determine the number of child and adult tickets sold is 4.50x + 6.50y = 382.50 and x + y = 65.
Step-by-step explanation:
The correct system of equations that can be used to determine the number of child tickets, x, and the number of adult tickets, y, sold is:
4.50x + 6.50y = 382.50
x + y = 65
This system can be obtained by setting up two equations based on the given information:
- Equation 1: The total number of tickets sold is 65. Since child tickets are represented by x and adult tickets by y, the equation becomes x + y = 65.
- Equation 2: The total amount collected from ticket sales is $382.50. Using the prices of child and adult tickets, the equation becomes 4.50x + 6.50y = 382.50.
Therefore, the correct answer is option D: 4.50x + 6.50y = 382.50, x + y = 65.
