Rory has 30 more jellybeans than Gigi who has 15 so Rory has 30+15 = <<30+15=45>>45 jellybeans
Rory has 45 jellybeans and Gigi has 15 so that's 45+15 = <<45+15=60>>60 jellybeans total
Lorelai has eaten three times the amount of jellybeans that both girls have so she has eaten 3*60 = <<3*60=180>>180 jellybeans
