AAA Michigan says gas prices statewide have risen by about 12 cents per gallon in the past week.
The Dearborn-based auto club says Monday that the average price for self-serve regular unleaded gasoline was about $2.21 per gallon. That's about 35 cents more than it was at the same point last year.
The lowest average price was about $2.19 per gallon in the Detroit area, while the highest average was about $2.27 per gallon in the Jackson area.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
