Question 958448
let x be the number of children and y be the number of adults, then
50x + (50 < c < 500)y = 28149
we are given x = 70
3500 + ( 50 < c < 500 )y = 28149
( 50 < c < 500 )y = 24649
note that the square root of 24649 is 157, therefore
157y = 24649
y = 157
157 adults attended and the cost of an adult ticket is $157
