Answer:
<h2>D. 16 represents the cost of a child ticket for the Bryant reunion.</h2><h2>G. Together the family spends $296</h2>
Step-by-step explanation:
To find the right answer we have to solve the system of equation:

If we multiply the second equation by -2, we could eliminate the c-variable and solve for a-variable:

Now, we replace this value in one equation to obtain the other value:

So, the solution of the system is
, which means that there are 8 adults and 5 children.
Also, according to the linear expressions The Bryants spend $12 per adult and $16 per child, and a total amount of $176. The Jordan family spend $10 per adult and $8 per child, and a total amount of $120. Both families together spent $296.
Therefore, the right answers are D and G
