Well, that's going to be a whole lot of burgers. As a whole, running on empty necessitates her refueling about 12500 tons, give or take. A large burger is somewhere around 500 grams, 2 for a kilo, 2000 for a ton, 25 million for a full fuel resupply.
25 million burgers should be somewhere around 100 - 200 million dollars, depends on the burger in question.
The hunger of a famished New Jersey is truly a sight to behold.
I mean, picture the typical fast food joint teen staring at Jersey's boobs and repeating "25 million burgers... 25 million burgers..." *faints*
Though his boss will basically go "I do not care from whence the burgers flow, only that they flow!"
