Question

Benito spent $1691 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for gasoline. If he drove 7138 miles, what was the average cost of the gasoline per mile?
Operating Expenses
Insurance $831
Registration $174
Maintenance $90
A. 1.05 cents
B. 8.35 cents
C. 60.97 cents
D. not enough information given

Answer 1

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.

Answer 2

D . it doesn't say how much he spent on gas
