Answer:
The number of children tickets sold was 610.
Step-by-step explanation:
Let
x ----> the number of adults tickets sold
y ----> the number of children tickets sold
we know that
x+y=1710 -----> equation A
50x+25y=70250 ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (1100,610)
therefore
The number of children tickets sold was 610.
