Professor Bryan noticed that gas is $0.20 cheaper in Madison (where he teaches at a satellite campus) than in Athens (where he lives). He is wondering if it will save him money to fill up each of his cars in Madison. He has a 2000 Dodge Caravan that gets 25 miles per gallon and has a gas tank of 18 gallons. He also has a 2006 Lancer that gets 30 miles per gallon and has a 13 gallon tank. If the distance between Madison and Athens is 30 miles, does it save Bryan money to drive to Madison to buy gas for each of his cars since he has to drive there twice a week anyway? Specifically, does the fuel efficiency savings from driving the Lancer outweigh the price savings from filling the Caravan with cheaper gas?
