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?

operating expenses:
expense
cost

insurance $972
registration $114
maintenance $105

The answer is $.085. This is the cost of the gasoline per mile. I got the answer through adding all the expenses (insurance, registration, and maintenance) which added up to $1191 and then subtracting it from $1837, which gets me $646. Lastly, I computed for the cost of gasoline per mile through dividing $646 by 7600 miles. I got .085.

Ithink if im not mistaking b is -3 but im not a 100% sude

500 dollars and its probably more than that
