2 adults and 4 children are going to disney it cost $107 for adults and $101 for kids. They dont want to spend more than $650 and want to give the kids the same amount of money to spend at the park after buying the tickets. how much money can they spend on tickets?

the tickets cost

2*107 + 4*101 = 618

so, if they give each kid $x, you need

618+4x <= 650
