As many of you know, our truck's fuel gauge doesn't work and we have to keep track ourselves. When we cap it off, it's pretty easy to see how many gallons were left as all you have to do is take the number of gallons your tank holds—in our case, 18—and subtract the number of gallons put in: http://www.popularmechanics.com/cars/how-to/a2633/4252585/ For example, when we capped the truck off on February 28, we put in 13.861 gallons of fuel. Doing simple math, we then know we had 4.139 gallons of fuel remaining (18 - 13.861 = 4.139). However, the problem comes when you partially fill it and don't cap it. For example, we put in $10.00 yesterday which gave us 3.745 gallons of fuel. Obviously, we can't do 18 - 3.745 = 14.255 because that would be wrong, so what are the calculations there?

So now we have a cushion of 175.0 miles, give or take.
