Gas prices in Rhode Island are up by two cents this week.

AAA Northeast said Monday the price of self-serve, regular is averaging $2.25 per gallon. That's the same as the national average but three cents higher than the average price in the state a year ago at this time.

AAA found the price of self-serve, regular selling for as low as $2.09 to as high as $2.40.

AAA officials say the increase follows a period of "solid demand and some declines in the glut of crude oil" that have kept prices low this summer.
