Gas prices increased from last week, AAA Michigan reports. Michigan's current statewide average is about $2.29 per gallon, about five cents more than last week's average. It's the third week in a row that weekly gas prices have risen above $2.

Of the cities surveyed by AAA, the cheapest price for self serve, unleaded fuel can be found in the Flint area, where it's about $2.22 a gallon. The highest averages can be found in the Traverse City area where it's about $2.36 per gallon.
