Answer this question:A couple with two children, ages 6 and 10 years old, decided to go to an amusement park. The regular ticket costs $109, but children below 12 years old have a $5 discount. If they gave the cashier $500, how much change will they receive?
The ticket costs 109 - 5 = $104 for each child. So the ticket cost of the two children is 104 x 2 = $208. The couple needs to pay the regular price, so it's 109 x 2 = $218. Thus, the family needs to pay a total of 208 + 218 = $426. Therefore, their change is 500 - 426 = $74.
The answer is 74.
