Best ResponseYou've already chosen the best response.02x + 2y = 24.50 multiple by 2 = 4x + 4y = 49 3x + 4y = 37.25 multiple by 1 = 3x + 4y = 37.25 then 4x + 4y = 49 3x + 4y = 37.25   x + 0 = 11.75 x = 11.75

Best ResponseYou've already chosen the best response.0let x = # adult ticket and y = # children ticket then we have a constraint: 1. theatre capacity is 500 ticket so, x+y = 500 2. ticket prices for adult = 10.50 and children = 5.50 so , 10.50x + 5.50y = 4700 until this can u understand?

Best ResponseYou've already chosen the best response.0theather capacity is 500 ticket so, we have to divide that theather for adult(x) and children (y) x+y = 500 > number of adult + number of children must be equal to 500
