If total child ticket sales were c, then
c + c+896 = 1904
2c = 1008
c = 504
So, if there are x children, each child ticket costs 504/x
and each adult ticket costs 1400/(2x) = 700/x
Now,
700/x = 504/x + 3.50
x = 56 children
check:
child sales: 56 * 9 = 504
adult sales: 112 * 12.50 = 1400
c + c+896 = 1904
2c = 1008
c = 504
So, if there are x children, each child ticket costs 504/x
and each adult ticket costs 1400/(2x) = 700/x
Now,
700/x = 504/x + 3.50
x = 56 children
check:
child sales: 56 * 9 = 504
adult sales: 112 * 12.50 = 1400
