he thought that obama was ripping us off because we're now paying 3.99 for 9/10ths of a gallon rather than for a full gallon. so he said the effective fuel price was 4.43/gal


And what do you think the price is per gallon if you pay 3.99 for 9/10ths of a gallon?




Who cares when the price on the sign is 3.999 per gallon, not 3.99 for 9/10ths of a gallon?

He thought the 9/10 part of the price on the signs was for getting 9/10th of a gallon....

It simply means 3.999 ... not 4.43

Wiki posted:

In mathematics, the harmonic mean (sometimes called the subcontrary mean) is one of several kinds of average. Typically, it is appropriate for situations when the average of rates is desired.



The 5th grade math some of you guys were trying to use is appropriate for a lot of things but not for calculating the average of a rate. For that you need to use the college level stuff.

Holy crap, Paul was actually (kinda) right about something in spite of himself. They do use a harmonic mean for the CAFE standards.

and gas as nothing but went up, Obama wants Fuel-efficient cars that average nearly 55 miles ....looks like gas will average 7 to 9.00 bucks for that Fuel-efficient 55MPG


so who's winning ?

I drive a 2008 Ford Focus. It is a base care with a standard transmission. I average 42.2 MPG around town and on the highways. I calculate my MPG per tank with two methods. 1) with a ScanGauge II and 2) with a pen and paper and they are always within .4 mpg of each other. I paid $12,400 for the car in '08. It is more cost effective than any Prius because it takes A LOT of gas to make up the nearly 10k in price difference.

Yes, I have a small car, but I only have to fill the tank once a month or so these days.

Maybe what Obama needs to do is look at why we don't have some fuel efficient cars available to us in the US, like:
