Subtract all his expenses from the amount he spent to operate, and what's left is the amount he spent on gas, which is $596.  If you then divide the number of miles he drove by the amount he spent, you get .08349.  But that is expressed in terms of dollars.  If it's in terms of cents, you have to multiply that number by 100 to get 8.35 cents, rounded to the nearest hundredth.
