Another way to think about it :
I fill up a little more than once a week, I drive 104 miles a day (52 one way) to get to work. I usually get approx. 10 gallons each time (12.8 gal. tank). If I drive 200 miles and fill up, and gas went up 10 cents during those 2 days, and another 10 cents the next 2 days, I have saved 50 cents versus filling up with 10 gallons after 4 days.
OR:
If I filled up at $3.50/gallon, and drive 400 miles it costs me 8.75 cents per mile.
Or you can drive 200 miles on $3.50/gallon gas at 8.75 cents per mile and the next 200 miles on $3.60/gallon gas at 9 cents per mile. You can fill up twice and go 400 miles for $35.50 or once for $35.00.
So which is cheaper?
