MIAMI - SEPTEMBER 15: Gas is pumped into a vehicle September 15, 2008 in Miami, Florida. Gasoline prices rose nearly 5 cents a gallon Monday, bringing the total increase in the three days since Hurricane Ike slammed into Texas to almost 17 cents, according to a nationwide survey. The average price of unleaded regular rose 4.7 cents to $3.842 a gallon, according to the survey released by motorist group AAA. That followed increases of 5.8 cents Saturday and 6.2 cents Sunday, which was the biggest one-day spike since after Hurricane Katrina hit the Gulf Coast in 2005 . (Photo by Joe Raedle/Getty Images)
