3) Anna is selling tickets to the school's gymnastics competition. On the first day, she sells 5 adult tickets and 6 child tickets for a total of $58.00. On the second day, she sells 8 adult tickets and 11 child tickets for a total of $97.00. Which system of linear equations can be used to determine the cost of each adult ticket (x) and each child ticket (y)?
A) 5x + 6y = 58 8x + 11y = 97
B) x + y = 155 x + y = 30
C) 5x − 6y = 58 8x − 11y = 97
D) x + y = 58 8x + 11y = 97

Answer:

I believe it's A) 5x + 6y = 58 8x + 11y = 97

Step-by-step explanation:

Reason is, adult tickets and child tickets are two different things, so they require two different variables, and two different equations because they have two different sums. (This was probably already obvious to you though).

Hope this helps :)

I tried my best to explain.
