Final answer:
To solve the problem, a system of linear equations was created representing the attendance on Thursday and Sunday. It was found that 568 people attended on Thursday and 1,704 people attended on Sunday.
Step-by-step explanation:
The question involves solving a system of linear equations. Let's define two variables: x for the number of people who attended on Thursday, and y for the number who attended on Sunday.
According to the problem, 3 times as many people attended on Sunday as on Thursday, which gives us the equation y = 3x. Also, we know that the total number of people who attended over the two days is 2,272, which leads us to a second equation, x + y = 2,272.
Substituting the first equation into the second gives us a new equation, x + 3x = 2,272, which simplifies to 4x = 2,272. Dividing both sides by 4, we find x = 568. That's the number of people who attended on Thursday. To find the number of attendees on Sunday, we go back to the equation y = 3x and substitute x with 568, resulting in y = 3 * 568 = 1,704.
Therefore, 568 people attended on Thursday, and 1,704 people attended on Sunday.
