DEARBORN (AP) -- AAA Michigan says gasoline prices have risen about two-and-a-half cents during the past week to a statewide average of about $3.26 per gallon.

The auto club said Monday the average is about 31 cents per gallon less than last year at this time.

The average price for self-serve regular unleaded fuel in the Detroit area remained relatively unchanged over the past week and averaged about $3.25 per gallon.

Traverse City in Northern Michigan averaged $3.17 per gallon. Flint averaged just over $3.20.

A gallon of gas in the Ann Arbor area west of Detroit averaged nearly $3.30.

Dearborn-based AAA Michigan surveys 2,800 Michigan gas stations daily.
