Mass. gas jumps 13 cents

Gasoline prices have jumped an average of 13 cents per gallon in Massachusetts compared with a week ago, and are up an average of 33 cents in the past month.

AAA of Southern New England's statewide survey finds an average price of $2.97 for a gallon of regular, self-serve gasoline.

A month ago, gas averaged $2.64 per gallon.

Prices at the pump are being driven up by rising crude oil prices on the global market, which are approaching $100 per barrel.

The auto club says prices in Massachusetts are still 13 cents below the national average of $3.10 per gallon for regular, self-serve gas. (AP)
