Prior to adjustment at the end of the year, the balance in Trucks is $296,900 and the balance in Accumulated Depreciation—Trucks is $99,740.
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 $80,000 $15,000 250,000 miles — 21,000 miles 2 54,000 6,000 300,000 $14,400 33,500 3 72,900 10,900 200,000 60,140 8,000 4 90,000 22,800 240,000 25,200 22,500
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.
b. Journalize the entry on December 31 to record depreciation for the year.
Answer:
a. Depreciation Rate per Mile:
Truck 1 ($80,000 – $15,000) ÷ 250,000 = $0.26
Truck 2 ($54,000 – $6,000) ÷ 300,000 = $0.16
Truck 3 ($72,900 – $10,900) ÷ 200,000 = $0.31
Truck 4 ($90,000 – $22,800) ÷ 240,000 = $0.28
Total...........................................................................
Note: Mileage depreciation of $2,480 (31 cents × 8,000) is limited to $1,860 for Truck 3, which reduces the book value of the truck to $10,900, its residual value.
b. Dec. 31 Depreciation Expense—Trucks 18,980
Accumulated Depreciation—Trucks 18,980
