AAA Michigan says gas prices statewide have gone up about 9 cents in the past week.
The Dearborn-based auto club says the average price for self-serve regular unleaded gasoline was about $2.43 per gallon on Sunday. That's about 99 cents less than at the same point last year.
According to the auto club, gas prices statewide have gone up two weeks in a row.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state. The lowest average price was about $2.34 per gallon in the Marquette area, while the highest average was about $2.47 in the Traverse City area.
