<em>An adult ticket costs $205 and a child ticket costs $49.</em>
<h2>
Explanation:</h2>
Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:
<em>Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child </em><em>for $459</em><em>. How much does and adult and child ticket cost?</em>
To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:
- Two families are planning a trip to Disney.
- The Smith family bought tickets for 2 adults and 3 children for $557.
- The Jones family bought tickets for 2 adults and 1 child for $459.
Let:

For the Smith family:
Cost for the 2 adults:

Cost for the 3 children:

Total cost:

For the Jones family:
Cost for the 2 adults:

Cost for the 1 child:

Total cost:

So we have the following system of linear equations:

Subtracting (2) from (1):

Finally, <em>an adult ticket costs $205 and a child ticket costs $49.</em>
