BISMARCK, N.D. (AP) — The average price of a gallon of gas rose 7 cents in North Dakota over the past week.

AAA says the price now averages $4.17 per gallon statewide. That’s 28 cents higher than a month ago, and $1.32 higher than a year ago. In Fargo gas is averaging nearly $4.19 a gallon, KFGO reports.

Nationally, the average price is $4.59 per gallon.

Petroleum analyst Patrick DeHaan, with the price-tracking website Gas-Buddy, says prices over the Memorial Day weekend will likely be $1.50 higher than they were last year. But, DeHaan says there are indications that price increases are slowing down.
