Answer:
$240,000
Explanation:
To calculate the depreciation value using the double declining balance method we should only consider the purchase cost of the equipment and not the salvage value.
$400,000 / 5 years = $80,000 per year
Since we use the double declining balance method the depreciation for year 1 will be $80,000 x 2 = $160,000
So the book value at the end of year 1 will be $240,000 (= $400,000 - $160,000).
