Answer:
The number of children's tickets sold was 27
Step-by-step explanation:
Let
x ----> the number of children's tickets sold
y ----> the number of adult's tickets sold
we know that
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A

solve for x



therefore
The number of children's tickets sold was 27
since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75
