AAA Michigan: Statewide average gas prices jump 20 cents

DEARBORN, Mich. (AP) — AAA Michigan says gas prices statewide have jumped by about 20 cents per gallon in the past week amid tighter supplies in the Great Lakes region.
       The Dearborn-based auto club says early Monday the average price for self-serve regular unleaded gasoline was about $2.72 per gallon. That's about 54 cents more than at the same point last year.
       Michigan's lowest average price was about $2.61 per gallon in the Traverse City area. The highest was about $2.79 per gallon in the Marquette area. It's the second consecutive week that the Marquette area had the highest reported average price.
       The Detroit-area's average rose about 24 cents to $2.78 per gallon.
       AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state.
