AAA Michigan says gas prices statewide have risen by about 9 cents per gallon in the past week. The Dearborn-based auto club says the average price for self-serve regular u nleaded gasoline was about $2.36 per gallon on Sunday. That’s about 39 cents less than it was at the same point last year. This is the first time in five weeks that the statewide price of gas has increased. The lowest average price was about $2.29 per gallon in the Traverse City area, while the highest average was about $2.42 per gallon in the Ann Arbor area. In Benton Harbor and St. Joseph, we have the second-lowest average price at $2.30.
