Equipment acquired at the beginning of the year at a cost of $12,000 has an estimated residual value of $2,000 and an estimated useful life of 5 years. How much would the equipment depreciate in a year when the double-declining-balance depreciation method is used? A fixed asset is originally purchased for $1,000 and over the course of its use it depreciates by $775. Then, it's sold for $100 when it's book value is $225. Prepare a journal entry for this sale and then determine which answer choice best represents that journal entry
