WASHINGTON — Gas prices have been declining over the past week after increasing steadily earlier in July.

In a weekly report Sunday on the price of gas, AAA Mid-Atlantic says the national average dropped to $3.65 per gallon on Friday. That’s a 2.5-cent drop in the past week.

But the cost is still 11 cents more expensive than a month ago and 16 cents more expensive than a year ago.

AAA Mid-Atlantic spokesman John Townsend says the decline in gas prices over the past seven days offers motorists a small sign of relief ahead of August vacations.

The average price in the District of Columbia was $3.89 on Sunday. Maryland drivers were paying $3.69 on average, and Delaware drivers were paying $3.67. Virginia had the lowest price in the region at $3.48.
