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 $65, determine the depreciation for the first year by the following methods:

a. Straight-line

b. Double-declining-balance

c. Units-of-activity (4,550 copies were made the first year)
