Answer:
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Step-by-step explanation:
First, we need to establish a system of equations:
x= number of adults tickets
y= number of senior citizen tickets
x + y= 400
6x + 3y= 2,070
Now, we isolate x in one equation and substitute the value in the other:
x= 400 - y
6*(400 - y) + 3y = 2,070
2,400 - 6y + 3y = 2,070
330 = 3y
110 = y
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Prove:
290 + 110= 400
6*290 + 3*110= 2,070
