gas prices rise

Gasoline prices climbed Friday for the 24th straight day as service stations pass along the rising cost of oil. The national average for gasoline hit $3.741 per gallon, according to AAA, Wright Express and Oil Price Information Service. That's an increase of 46.5 cents per gallon since the start of 2012. Gasoline has never been so high this time of year, and analysts say it could reach a record of $4.25 per gallon by late April.

Inflation in 2010 was low, according to the consumer price index. But underlying growth in the cost of energy, raw materials and health care could indicate significant inflation this year. And that could mean higher prices for consumers or lower profits for companies.
