Question

Depreciation by units-of-activity Method

Prior to adjustment at the end of the year, the balance in Trucks is $400,300 and the balance in Accumulated Depreciation—Trucks is $124,060. Details of the subsidiary ledger are as follows:

Truck No.	Cost		Estimated Residual Value		Estimated Useful Life		Accumulated Depreciation at Beginning of Year		Miles Operated During Year
1	$77,000		$11,550		220,000	miles	—		33,000	miles
2	111,800		13,416		330,000		$22,360		33,000
3	99,000		13,860		212,000		$79,200		21,200
4	112,500		13,500		320,000		$22,500		38,400

a. 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.

Truck No.	Rate per Mile (in cents)		Miles Operated		Credit to Accumulated Depreciation
1	$		33,000		$
2	$		33,000		$
3	$		21,200		$
4	$		38,400		$
			Total		$

b. Journalize the entry to record depreciation for the year.

			_____ ______

Answer 1

1)
Truck No.	Rate per Mile = (Cost (-) Residual Value) / Useful life	Miles Operated	Credit to Accumulated Depreciation
1	$ 0.30 ($ 77,000 (-) $ 11,550) / 220,000	33,000	$ 9,900
2	$ 0.30 ($ 111,800 (-) $ 13,416 ) / 330,000	33,000	$ 9,900
3	$ 0.40 ($ 99,000 (-) $ 13,860) / 212,000	21,200	$ 5,940 ( $ 99,000 (-) $ 13,860 (-) $ 79,200)
4	$ 0.31 ( $ 112,500 (-) $ 13,500 ) / 320,000	38,400	$ 11,904
Total			$ 37,644
