If Coraline has the number 80, Jayden, whose number is 40 less than that of Coraline, has 80-40 = <<80-40=40>>40
Together, Jayden and Coraline's numbers total 80+40 = <<80+40=120>>120
Mickey's number is greater than Jayden's number by exactly 20, meaning his number is 40+20 = 60
The total of the numbers the three have is 120+60 = <<120+60=180>>180
