Determine for each truck the depreciation rate per mile and the amount to be credited to the accumulated depreciation section of each subsidiary account for the miles operated during the current year. Keep in mind that the depreciation taken cannot reduce the book value of the truck below its residual value. Round the rate per mile to two decimal places. Enter all values as positive amounts.

Units-of-production allocates the cost of the asset equally over the units produced. The depreciation rate stays constant, no matter how many miles are driven each period. Keep in mind that the depreciation taken cannot reduce the book value of the truck below its residual value. b. Journalize the entry to record depreciation for the year.
