Answer:
![x+y=12](https://tex.z-dn.net/?f=x%2By%3D12)
![21.50x+14.75y=204](https://tex.z-dn.net/?f=21.50x%2B14.75y%3D204)
Step-by-step explanation:
Let x be the number of adult tickets and y be the number of children's tickets.
We are given that there are total 12 people. Therefore, we can set:
![x+y=12](https://tex.z-dn.net/?f=x%2By%3D12)
Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be
and cost of y children's ticket will be
. We can form the second equation by setting the total cost of tickets as:
![21.50x+14.75y=204](https://tex.z-dn.net/?f=21.50x%2B14.75y%3D204)
Therefore, the required system of equations that could be used to find x and y will be:
![x+y=12](https://tex.z-dn.net/?f=x%2By%3D12)
![21.50x+14.75y=204](https://tex.z-dn.net/?f=21.50x%2B14.75y%3D204)
A, it is has 6 sides so it equals 6/6 each individual side is 1/6
