AAA Michigan says average gas prices statewide have risen about nine cents in the past week to about $2.99 per gallon.
The Dearborn-based auto club said Monday that the average price for self-serve regular unleaded gasoline is about 69 cents more than at the same point last year.
Michigan's lowest average price was about $2.87 in the Marquette area. The highest was about $3.06 in the Ann Arbor area.
AAA says it's the ninth week in a row that the Ann Arbor area has had the highest average. The Detroit-area's average was about $3, up five cents per gallon.
