Question

Benito spent $1689 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for gasoline. If he drove 8482 miles, what was the average cost of the gasoline per mile.

Operating expenses
Insurance $882
Registration $181
Maintenance $116

Answer 1

$1689 - $882 - $181 - $116 = Cost of gasoline.

Cost of gasoline = $510

$510/8482 = 0.06$ (2 d.p.) per mile

Answer 2

The average cost of the gasoline 6.02 cents. ( approx )

Explanation:

Given,

Total spending = $ 1689,

Expenses are,

Insurance = $ 882

Registration = $ 181

Maintenance = $ 116

Thus, the total expenses = $ 1179

And, the spending on gasoline = Total spending - total expenses

= $ 1689 - $ 1179

= $ 510,

= 51000 cent ( 1 dollar = 100 cent )

Now, it is given that he drove 8482 miles,

Hence, the average cost of the gasoline per mile =
`(51000)/(8482)` = 6.01273284603 ≈ 6.01 cent.
