Answer:
18 children
Step-by-step explanation:
Given

<em>Required (missing part of the question):</em>
<em>Number of children that will be able to go to the zoo if 8 adult tickets are purchased</em>
  
<em>The graph is missing. However, the question can be solved without the graph.</em>
<em />
From the question and equation, we can deduce the following:
- x represents adults
- y represents children
So, when 8 adult tickets were sold. 
This means

Substitute 8 for x in 


Subtract 96 from both sides



Solve for y


<em>This means that 18 children will be able to go</em>
