Maintenance $57



A. 61.06 cents


B. 10.71 cents


C. 1.27 cents


D. not enough information

Answer 1

Answer is B) 10.71 cents.

You just add Benito's operating expenses togther, like so:

809 + 170 + 57 = $1036 so far.

Next, subtract the total amount he spent this last year (1822), with how much he spent so far (1036).

1822 - 1036 = $786

Finally, divide the final total with the 7340 miles he plans to drive.

786 ÷ 7340 = 0.10708

Answer is B) 10.71 cents.

Answer 2

B. 10.71 cents

Explanation:

Benito's other expenses total ...

$809 +170 +57 = $1036

so his gas expense is ...

$1822 -1036 = $786

Then the per-mile cost is ...

$786/(7340 mi) ≈ $0.10708/mi

Benito's gas cost averaged 10.71¢ per mile.
