A grandma wants to go to the South of France over the weekend,but she cannot decide if she wants to take a plane,a taxi or a train.The cost of each transportation mean was written on a piece of paper,but sadly the grandma lost her glasses.All she can remember is that plain flight cost the same amount as the train and the taxi ride put together.Also,that the train ride cost half as much as the taxi ride.Altogether the plane flight,train ride and taxi ride cost 754.50CHF(Swiss Franc). How much does each individual transportation mean cost?  ♥
