the mason family went to the amusement park. they spent 56.00$ on tickets. if adults cost 12$ and kids cost 5$ how many adults and children went to the park?

math - Reiny, Thursday, February 23, 2012 at 8:31pm
assuming there is one mom and one dad, let the number of kids be x

2(12) + 5x = 56
5x = 32
x = 32/5 , well, that's no good

let the number of adults be x, number of kids be y
12x + 5y = 56
looking for integer solutions,
let y = 4
12x + 20 = 56
x = 3

3 adults, and 4 kids
