I’m not sure how the chart works but here’s how to solve the problem.

First creat two inequalities with the values given using x as the number of student ticked and y as non student.

X + y = 292 tickets

Notice how this measures only the tickets

The next equation is the cost and total earnings.

1x + 3y = $470

Notice these values are in dollars not tickets.

Now pick one equation and solve for one variable. We will use the x variable and the first equation.

X + y = 292

Get x by itself to find the equality by subtracting y from both sides.

X = 292 - y

Now we have a value for x that we can use to solve the second equation. Plug the right side of the equation in for the x value since they are equal

1(292-y) + 3y = 470

Now solve for y

292 - y + 3y = 470

2y + 292 = 470

2y = 178

Y = 89$

Now use this value for y in the second equation again.

X + 3(89) = 470

X + 267 = 470

X = 203$

This means that student ticket sales totals 203$ while non student totals 89$

In this specific case this also means that:

Student tickets sold = 203 tickets
Non student tickets sold = 89 tickets
