Step-by-step explanation:
We know that
• 9 tickets cost $54.
,
• Adult tickets cost $8.
,
• Child ticket costs $3.50.
Let's call <em>x</em> adult tickets and <em>y</em> child tickets.
Using the given information, we can define the following.
Because Jose bought 9 tickets in total.
Then, we express another equation.
This equation represents the costs.
Let's isolate <em>y</em> in the first equation.
Then, we replace this last expression in the second equation.
We solve for <em>x</em>.
<h2>Therefore, Jose bought 5 adult tickets.</h2>
