Answer:
<u><em>Units-of-activity Depreciation : $ 13,770</em></u>
<u><em>Double Declining Method Depreciation For the Second Year= $ 9120</em></u>
Explanation:
Formula: Units-of-activity Depreciation
Annual Depreciation= Depreciable Value×Units produced during the year/Estimated total production
<em><u>Annual Depreciation</u></em> = $ 51,000 * 27000/100,000
= $ 13,770
Depreciable Value = Original cost – Scrap value
<u><em>Depreciable Value</em></u> = $57000 - $6000= $ 51000
Formula : Double Declining Method
Double Of Straight Line Method Depreciation Rate = 2 * 1/10= 2* 10%= 20%
20 % of $ 57,000 for the first year= $ 11,400
<u><em>Depreciation </em></u>20 % of $ 45,600 for the second year= $ 9120
