In December 2009, the price of crude oil was $70.53 per barrel.
1979 was the last time gasoline was actually selling for $1.00. But if you adjust the price for inflation the price was below $1.00 in 2008.
It is hard to certain but it seems that gas price wil fall by a considerable amount by Christmas. The price of oil has dropped $50 a barrel in the last month. I would expect gas prices to drop by 75c to a dollar a gallon by Christmas.
Oil reached $97.00 a barrel in 2008. That year, the average price for a gallon of regular gasoline was $3.27
In 1995 the average price of gas per gallon was $1.11. Oil was an average of $16.75 per barrel for the year.
There is no logical answer to this question. Gas at my local Arco was $1.55 when oil was $45 a barrel. Now oil is $36.00 a barrel and gas has risen to $1.99. This is a clear case of price fixing and manipulation. The oil companies are hoping we are so happy with sub $4.00 gas that we wont notice the sneaky ratching up the the price when it should be falling. Based on my calculations gas should now be $1.24 a gallon or 34.45% of the price of a barrel of oil.
It jumped to $90 a barrel and gas followed from 2.77 to 3.00
The last time that price would've been seen was probably the Summer/early Autumn of 1999.
Because the price per barrel has dropped, and when the gas company has taken enough of our money they lower the price.
The price of gas is a variable, because the price changes from time to time. A constant would be something such as the number of fluid ounces in a gallon.
The price of has drastically changed over time. In 1999, the average price of gas was under one dollar.
The price of natural gas is currently $4.16. The price has been rising steadily for the last few months. One can monitor it's price on the US Energy Information Administration website.
