$25,000 - 5,000 = $20,000
Since the useful life is 10 years or 10% per year, double-declining rate would be 20%
Year 1
$20,000 x .2 = $4000
Book Value = $16,000
Year 2
$16,000 x .2 = $3,200
Book Value = ($16,000-3,200) =$12,800
The answer is going to be 27 as x so 27-21=6 to check you can do 6+21 which would equal to 27 so that’s the answer.
THE WAY YOU CHACK THE ANSWER IS BY SUBTRACTING 31-17 AND SEEING IF IT GIVES YOU 14 OR THE OTHER WAY AROUND
