The price of petrol (gasoline) that needs to be paid to make back how much you spent looking for petrol.
'1 dollar and 10 cents, thats the price of petrol we need to make back how much we spent looking for petrol. The farthur we go, the cheaper the petrol needs to be. I call it the Annabelle's principle.'
