Rearrange in decreasing exponents.

The depreciation of the car is $12,600.
The cost of the car per mile is $0.28
<h3>What is the depreciation of the car?</h3>
Depreciation is the decline in the value of an asset as a result of wear and tear.
Depreciation = cost of the asset - value of the asset now
$24,890 - $12,290 = $12600
<h3>What is the cost per mile?</h3>
Cost per mile = total cost / total mile
($2,805.60 + $1,870.40) / 16700 = $0.28
