A copy machine was purchased for $35,000. The machine is estimated to have a useful life of four years with a residual value of
$3,000. It is estimated that the machine will make 2,000,000 copies. Using the units-of-activity method to depreciate the copy machine, what information is needed to calculate the first year's depreciation if 550,000 copies were made? a.$35,000 cost, useful life of four years, 2,000,000 copies, and $3,000 residual value b.$35,000 cost, useful life of four years, and $3,000 residual value c.$35,000 cost, 2,000,000 copies, $3,000 residual value, and 550,000 copies made d.$35,000 cost, 2,000,000 copies, and $3,000 residual value
