Okay, I just made a new spreadsheet that calculates the price that E85 "should" be.
The spreadsheet goes out to the CBOT and Nymex websites and gets the price of ethanol and unleaded from yesterday. It takes 85% of the price of ethanol, 15% of the unleaded price, adds the gas tax (51 cents in Indiana) and a 3 cent freight charge.
It's telling me that E85 should be $3.54 a gallon.
Point of fact, it is $3.52 a gallon right now at Meijer. And E85 is NOT 85% ethanol right now, so it should even be a little more expensive.
Now I have the spreadsheet, I need how to make a widget that refers to it.
