The retail price of gasoline rose to an average of $1.87 per gallon, the Energy Department reported Monday.
The government survey said the average price nationwide of regular-grade unleaded gasoline increased 2 cents last week to $1.866. Prices are 22.3 cents higher than a year ago.

Pump prices are highest on the West Coast, averaging $2.034 per gallon, and cheapest on the Gulf Coast, averaging $1.757 per gallon. In the Midwest, gas averages $1.848 per gallon.
One of the key factors behind the high price of gasoline is the soaring cost of oil, the result of terrorism fears, strong demand and supply concerns.
