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?

How much does each child's ticket cost? ** The ticket costs 109 - 5 = $<<109-5=104>>104 for each child.
How much does the two children's tickets cost? ** So the ticket cost of the two children is 104 x 2 = $<<104*2=208>>208.
How much does the couple need to pay? ** The couple needs to pay the regular price, so it's 109 x 2 = $<<109*2=218>>218.
How much does the family need to pay? ** Thus, the family needs to pay a total of 208 + 218 = $<<208+218=426>>426.
How much change will they receive? ** Therefore, their change is 500 - 426 = $<<500-426=74>>74.
