Answer:
$31 per ton
Explanation:
The computation of Cost of Goods Sold is shown below:-
Depreciation of mine per ton of extracted ore
= ($3,800,000 - $200,000) ÷ 2,000,000 tons
= $1.80 per ton
Depreciation of building and Equipment = $1,800,000 ÷ 2,000,000 tons
= $0.90 per ton
Quantity of ores mined in the first year = 750,000 tons
Depreciation to be allocated
Mine = 750,000 × $1.80
= $1,350,000
Building & equipment = 750,000 × $0.90
= $675,000
Total cost of goods sold in the first year = Depreciation + labor cost
= ($1,350,000 + $675,000 ) + $300,000
= $2,325,000
Cost of goods sold per ton =Total cost of goods sold in the first year ÷ Tons
= $2,325,000 ÷ $750,000 tons
= $31 per ton
