A government worker whose personal car gets 24 miles to the gallon was required to use his own car for government business. He filled the tank before he began, requiring 18 gallons, for which he paid $1.349 per gallon. He drove 336 miles, then filled the tank again at a cost of $1.419 per gallon. The government reimburses him at the rate of $0.20 per mile. What was the actual cost of gasoline for this trip?
