A copy machine acquired with a cost of $1,410 has an estimated useful life of 4 years. It is also expected to have a useful operating life of 13,350 copies. Assuming that it will have a residual value of $75, determine the depreciation for the first year by the (a) straight-line method (b) double-declining-balance method (c) units-of-output method (4,500 copies were made the first year)
