A group of adults and kids went to see a movie. Tickets cost $6.00 each for adults and $2.50 each for kids, and the group paid $41.50 in total. There were 3 fewer adults than kids in the group.
Find the number of adults and kids in the group.
let x=number of kids
x-3=number of adults
..
2.50x+6.00(x-3)=41.50
2.5x+6x-18=41.5
8.5x=59.5
x=7
x-3=4
number of kids=7
number of adults=4
