Due to a computer crash, some accounting data were corrupted at Ace Industries. For the Furniture account, only some of the data were still accessible. The balance in the Accumulated Amortization-Furniture account was $75,000. The furniture had been amortized a total of 60 percent of its original cost. Prior notes indicate that the double-declining-balance method was used for all furniture. The estimated useful life was eight years, and its residual value is expected to be 20 percent of its original cost.
