AUGUSTA (AP) — The average retail cost of a gallon of gas has gone up a little over a penny over the past week.

Price-monitoring website MaineGasPrices.com reported Monday that the price is averaging $3.49 a gallon.

In-state prices remain 25 cents above the national per-gallon average of $3.21.

Maine prices are 10.7 cents per gallon higher than a month ago and 0.6 cents per gallon higher than at this time last year.

The price is based on a survey of more than 1,200 Maine gas stations.
