Answer:
A
Explanation:
Let's say x represents adult tickets, and y represents child tickets.
We know that 2 adult tickets, x, and 2 child tickets, y, added together total $26. This can be written as:
2x+2y=26
We also know that 2 adult tickets, x, and 3 child tickets, y, added together total $31. This can be written as:
2x+3y=31
So, our system is:
2x+2y=26
2x+3y=31
Therefore, choice A is correct.
