Notes -
You can take a few seconds longer and just brute-force the calculation through 15 gallons. I guess the problem is that using math to solve problems feels like work to a large percentage of the population, so they don't do it if they can get away with not doing it. Why keep a rough running total of your shopping cart contents in your head when the cashier will just ring it up and you can just pay with your credit card? If you really must reduce your spending, then you can just sit down, get your calculator out and do work.
