Answer:
Number of students tickets sold= 184
Number of adults tickets sold= 192
Step-by-step 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
