The average fuel price in California is______.

(28)A sharp rise in fuel prices in California linked to state supply shortages has forced some petrol stations to close temporarily.
    (27)In one part of the Golden State, prices hit $5. 69 a gallon, $1.20 more than the California average. The situation has been magnified by pollution limits requiring a special fuel blend during the summer. Officials insisted California was not running out of petrol, and one refinery has already resumed production. The refinery had gone offline because of a power cut, exacerbating the supply problems.
    Fuel price spikes particularly affect the state’s independent petrol station operators, who pay a higher price for their supplies than some national chains. Some have closed down their pumps rather than cut into profit margins. Costco, a giant discount store chain that sells large volumes of petrol, closed 14 of its 40 Los Angeles-area stations. Five were expected to reopen on Friday.
