AAA Michigan says gas prices statewide have risen by about 10 cents per gallon in the past week.
The Dearborn-based auto club says early Monday that the average price for self-serve regular unleaded gasoline was about $2.34 per gallon.
That's about 13 cents less than it was at the same point last year.
It's the second week in a row that the statewide average has increased.
The lowest average price was about $2.28 per gallon in the Benton Harbor area, while the highest average was about $2.37 per gallon in the Bay City, Midland and Saginaw areas.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
