NEW YORK — Hamburgers, health care, and taxes are all set to take a bigger bite out of the family budget this year. But drivers’ annual gas bills are expected to drop for the first time in four years.

Forecasters say ample oil supplies and weak US demand will keep a lid on prices. The lows will be lower and the highs won’t be so high, compared with a year ago. The average price of a gallon of gasoline will fall 5 percent to $3.44, according to the Energy Department.
