Summer gas prices at lowest level in more than a decade

The average price of a gallon of gasoline in Massachusetts ticked down 3 cents this week to the lowest price at this point in the summer in more than a decade, AAA reported Tuesday, and the cost of gas is expected to remain low into the fall.
The average price of self-serve regular gas is $2.05 this week, 7 cents lower than the national average and the lowest average price in Massachusetts since mid-April, AAA said. At this time in 2015, the average price of a gallon of gas was $2.52.
