DEARBORN, Mich. (AP) -- AAA Michigan says gasoline prices are up 2.5 cents per gallon over the past week to a statewide average of $3.13.
The auto club says Monday the statewide average is 47.5 cents per gallon higher than last year at this time.
Spokeswoman Nancy Cain says the report compares prices from a week ago Monday. Last week, because of the Martin Luther King Jr. Day holiday, the auto club reported Tuesday a statewide average of $3.13.
Of the cities it surveys, AAA Michigan says the cheapest price for self-serve regular fuel is in the Saginaw/Bay City area, where it's $3.08 a gallon. The highest average can be found in the Marquette area at $3.17.
Dearborn-based AAA Michigan surveys 2,800 Michigan gas stations daily.
