AAA Michigan says gas prices statewide have fallen by about 7 cents per gallon in the past week.
The Dearborn-based auto club says the average price for self-serve regular unleaded gasoline was about $2.17 per gallon on Sunday. That's about 35 cents less than it was at the same point last year.
It's the second week in a row that the statewide average has dropped.
The lowest average price was about $2.07 per gallon in the Grand Rapids, Muskegon and Holland areas, while the highest average was about $2.27 per gallon in the Marquette area.
AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
