Answer:
Accumulated depreciation is $13,000
Step-by-step explanation:
Net book value =Cost-Accumulated depreciation
Accumulated depreciation=Cost -Net Book Value
Cost is $25,000
Net Book Value is $12,000
Accumulated depreciation=$25,000-$12,000
Accumulated depreciation=$13,000
The accumulated depreciation is usually the cost of an item less net book value at end of a period,the accumulated depreciation is $13,000 till date.
The salvage value would been useful if we compute depreciation, which can be done since the useful life of the equipment is not given i,e (cost-scrap value)/useful life.
