LETTER TO THE EDITOR: Mathematics can explain high prices

To the editor:

There are gasoline refineries as close as 25 miles to Whidbey Island.

Yet, the price of gasoline is about 25 cents higher than distant cities.

As a result, we’ve come up with a formula for the retail pricing of gasoline, called “Earl’s Law.”

Earl’s Law: The price of gasoline at the pump is inversely proportional to its distance from the nearest refinery.
