Final answer:
The difference between the book value of the video-recording system after three years of DDB depreciation and the trade-in value is $1,708.
Step-by-step explanation:
The question involves calculating the difference between the book value and the trade-in value of a video-recording system using the Double Declining Balance (DDB) method of depreciation. The original cost of the system was $38,000, and it has been depreciated over 3 years of its 5-year recovery period.
Calculating the depreciation, we first take two times the straight-line depreciation rate. Since it's a 5-year period, the rate is 20% per annum, doubled to 40% for DDB. For the first year, the depreciation is 40% of $38,000, which is $15,200, leaving a book value of $22,800.
In the second year, we again apply 40% to the new book value, leading to $9,120 depreciation and a new book value of $13,680. In the third year, depreciation is 40% of $13,680 which is $5,472, leaving a book value of $8,208. The difference between this book value and the trade-in value of $6,500 is obtained by subtracting $6,500 from $8,208, which equals $1,708.
