Please help me solve this question :)

On December 27, 2014, Cullumber Windows purchased a piece of equipment for $101,000. The estimated useful life of the equipment is either three years or 52,000 units, with a residual value of $5,500. The company has a December 31 fiscal year end and normally uses straight-line depreciation. Management is considering the merits of using the units-of-production or the diminishing-balance method of depreciation instead of the straight-line method. The actual numbers of units produced by the equipment were 8,000 in 2015, 15,500 in 2016, and 27,500 in 2017. The equipment was sold on January 5, 2018, for $15,000. (a) Calculate the depreciation for the equipment for 2015 to 2017 under 1. the straight-line method 2. the diminishing-balance method, using a 40% rate; and 3. units-of-production (Round depreciable amount per unit to 3 decimal places, e.g. 1.252 and the final answers to 0 decimal places, e.g. 126.) Depreciation Expense Straight-Line Diminishing-Balance Units-of-Production 2015 $ 2016 2017
