Gas Prices

As the gas prices keep dropping and dropping, I beginning to wonder how much I would pay for a week for my Dodge Charger. To fill up my Charger it would cost me 25 dollars a week to fill up my tank. I got that by doing 350(miles frove per week)/24mpg x $1.73=25.229. Last time I posted about gas prices it costed 57 dollars a week for gas. That is a difference of 34 dollars! 

I think the reason for the lower gas prices is a combination of things. One reason is that when gas prices were so high in the summer it got people of the roads. Now the oil companies want people driving again so the make gas affordable. Another reason for low gas prices is that  with unemployment rates going up, less people are driving to work and back which lowers oil consumption. Those are some of the reasons for the low gas prices.
