AAA Michigan says gas prices statewide have risen by about 4 cents per gallon in the past week.
The Dearborn-based auto club says early Monday the average price for self-serve regular unleaded gasoline was about $2.36 per gallon. That's about 12 cents less than at the same point last year.
AAA says the lowest average price was about $2.33 per gallon in the Marquette area. The highest was about $2.39 in the Ann Arbor area. It's the second consecutive week that the Ann Arbor area had the highest average.
The Detroit-area's average was relatively unchanged from last week at about $2.36 per gallon.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
