MPG VS. MP$

Wouldn't you think twice about getting a car or going unnecessary places if you change miles per gallon into miles per dollar.(although the used car salesmen might get a little mad.)

So, next time you go someplace, just think about how much you are spending. To calculate your MP$, click here.
