48 adult tickets and 24 children tickets were sold.
Step-by-step explanation:
Given,
Cost of one adult ticket = $8
Cost of one child ticket = $3
Total worth of sold tickets = $456
Let,
Number of adult tickets sold = x
Number of child ticket sold = y
According to given statement;
8x+3y=456 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 1 in Eqn 2

Dividing both sides by 19

Putting y=24 in Eqn 2

48 adult tickets and 24 children tickets were sold.
