A company purchased office equipment for 40000 and estimated
     A company purchased office equipment for $40,000 and estimated a salvage value of $8,000 at the end of its 4-year useful life. The constant percentage to be applied against book value each year if the double-declining-balance method is used is 20% 25%. 50%. 5%.  
  
  Solution
Solution:
(1) answer is 50%
working:
Double declining balance method rate = 2 x straight line method rate
= 2 x ( 1 ÷ Life of assets ) x 100
= 2 x ( 1÷4)x100
= 50%
( 2) answer is $75,000
working:
Depreciation per unit of activity = (Cost - salvage value )÷ Total machine hours
=( $240,000 - $15,000 ) ÷ 15,000
= $15
Depreciation for 2nd year= $15 x 5,000
= $75,000
