Simon Tam is negotiating passage on Serenity as a clandestine fugitive from the planet Persephone. He is told that the 219 million kilometer trip to Osiris will cost $3,030. Alternatively, he can take a 349 million kilometer trip to Bellerophon, but that will cost $4,330. If cost depends on distance, what is the fixed cost, and what is the variable cost, of the voyage to Bellerophon?
