Gas prices continue to rise, and are now at their highest level in seven years, according to the AAA Gas Price Index.
The national average price for a gallon of regular gasoline rose six cents over the past week to hit $3.38 on Monday, up $1.22 from a year ago, or an increase of 57 percent.
With an average tank size of 18.5 gallons, it now costs drivers an extra $22 every time they fill up - and even more in states where gas prices are higher than the national average.
