Answer:

Number of students tickets sold= 184

Number of adults tickets sold= 192

Explanation:

I assume we need to calculate the number of student and adult tickets sold.

First, we establish the system of equations:

x= number of students tickets sold

y= number of adults tickets sold

4*x + 7*y= 2,080

x + y= 376

Now, we isolate x in one formula and substitute it in the other:

x= 376 - y

4*(376 - y) + 7y = 2,080

1,504 - 4y + 7y = 2,080

3y = 576

y= 192

x= 376 - 192

x= 184

Number of students tickets sold= 184

Number of adults tickets sold= 192
