Answer:

(a) Straight-line depreciation.

depreciation expense per year = ($315,900 - $15,900) / 4 = $75,000

(b) Activity method for 2014 and 2015, assuming that machine usage was 15,000 hours for 2014; 11,710 hours for 2015; 12,150 hours for 2016 and 1,140 hours for 2017.

depreciation expense per unit = $300,000 / 40,000 = $7.50 per unit

depreciation expense 2014 = $7.50 x 15,000 = $112,500

depreciation expense 2015 = $7.50 x 11,710 = $87,825

(c) Sum-of-the-years'-digits.

depreciation expense 2014 = $300,000 x 4/10 = $120,000

depreciation expense 2015 = $300,000 x 3/10 = $90,000

(d) Double-declining-balance.

depreciation expense 2014 = $315,900 x 2 x 1/4 = $157,950

depreciation expense 2015 = $157,950 x 2 x 1/4 = $78,975

depreciation expense 2016 = $78,975 x 2 x 1/4 = $39,487.50

depreciation expense 2017 = $39,487.50 - $15,900 = $23,587.50
