Answer:
The constant percentage to be applied against book value each year is 40%
Step-by-step explanation:
Data provided in the question:
Cost of the equipment purchased by the company = $41,000
Estimated a salvage value = $8200
Useful life = 5 years
Now,
Under the double-declining-balance method,
the percentage rate of depreciation is given as;
=
thus,
for Useful life of 5 years, we have
the percentage rate of depreciation =
or
the percentage rate of depreciation = 0.4 × 100%
or
the percentage rate of depreciation = 40%
Hence,
The constant percentage to be applied against book value each year is 40%
