Winston Company uses the units-of-activity method in computing depreciation. A new plant asset is purchased for $42,000 that will produce an estimated 130,000 units over its useful life. Estimated salvage value at the end of its useful life is $4,000. Calculate the depreciation cost per unit. (Answer should rounded to the nearest to two decimal places, 1.e, 0.4666 would be entered as 0.47 )
