19. Book value of an asset is its historical cost less any accumulated depreciation.
20. Recording the depreciation recognized in the contra asset account allows the total cost of the

21. Book value is computed as the cost of the equipment less the accumulated depreciation of
that equipment, $5,000 − $3,000 = $2,000. This does not represent the fair market value of
22. The method of depreciation chosen for a particular piece of equipment should represent
as closely as possible the pattern of its usage of that piece of equipment. For instance,
23. When an asset is purchased and put into service, an estimate is made of the expected
useful life of the asset. However, as the asset is used, it may become apparent that the
estimate was incorrect or circumstances may have changed (e.g., the asset is used more
24. When an expenditure improves the quality of an asset, this improvement is accounted for as
if a new asset is purchased; the equipment account is debited. The improvement is
