Tennessee’s per-gallon average of regular unleaded gasoline was $3.13 as of this past weekend, a decrease of 4 cents per gallon from the previous week, according to AAA.
The mark compares to the national average price of regular unleaded gas of $3.35, which is also 4 cents less than last week’s figure.
Retail gas prices are forecast to decrease throughout the end of the year, AAA said. Both oil and gas prices dropped last week after the value of the dollar increased to a two-week high.
The value of the dollar increased against the euro after the U.S. Department of Labor announced the nation’s unemployment rate fell to 7.7 percent in November and Germany cut its economic growth outlook for 2013.
"Both oil and gas prices are forecast to decrease again this week on the expectation demand will continue to fall from last year's levels as supplies climb," Jessica Brady, AAA spokeswoman, The Auto Club Group, said in a release. "Although gas prices in the Southeast are still slightly higher than what motorists paid last year, the good news is they are expected to drop as the year-end holiday approaches."
A barrel of oil settled Friday at $85.93 on the New York Mercantile Exchange, $2.98 less than price from the week prior.
