Ineed with coming up with equation

Let's call a child's ticket and an adult's ticket . From this, we can say:

,

since 116 tickets are sold in total.

Now, we are going to need to find another equation (the problem asks us to solve a systems of equations). This time, we are not going to base the equation on ticket quantity, but rather ticket price. We know that an adult's ticket is $17,000, and a child's ticket is thus

.

Given these values, we can say:

,

since each adult ticket costs 17,000 and each child's ticket costs 12,750, and these costs sum to 1,653,250.

Now, we have two equations:

Let's solve:

We have now found that 75 child's tickets were sold. Thus,

,

41 adult tickets were sold as well.

In sum, 41 adult tickets were sold along with 75 child tickets.
