Since the regular ticket costs $109 and children below 12 years old have a $5 discount, the ticket for each child will cost $109 - $5 = $104.
The total cost for two children's tickets is $104 x 2 = $208.
So, the cost for the couple's tickets is $109 x 2 = $218.
The total cost for all tickets is $208 + $218 = $426.
If they gave the cashier $500, the change they will receive is $500 - $426 = $74.
