Question

Benito spent $1837 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for gasoline. If he drove 7600 miles, what was the average cost of the gasoline per mile?

Answer 1

I answered this question before. It lacked some data needed to solve this problem.

Operating Expenses 
Cost Insurance $972 
Registration $114 
Maintenance $105

1837 - 972 - 114 - 105 = 646 cost of gasoline

646 / 7600 = 0.085 or 8.5 centavos
