Given that Benito spent $1,627 to operate his car last year and that some of the expenses are $972, $114, and $105.

Given that Benito's only other expense was for gasoline. This means that the expense for gasoline is given by $1,627 - $972 - $114 - $105 = $436

If he drove 7675 miles, then the average cost of the gasoline per mile is given by $436 / 7,675 = $0.0568 = 5.68 cents per mile.
