Answer:
a. $23
b. $165,600
c. $455,400
Explanation:
The computation is shown below:
a. Per unit cost
= Cost of depreciation ÷ estimated number of tons
where,
Cost of depreciation = Purchase value of land + fair value of this restoration obligation + developmental costs incurred - residual value
= $1,031,000 + $99,900 + $222,000 - $111,000
= $1,241,900
And the estimated number of tons is 54,000 tons
So, the per unit cost would be
= $1,241,900 ÷ 54,000 tons
= $23
b. The total material cost for ending inventory would be
= (27,000 tons - 19,800 tons) × $23
= 7,200 tons × $23
= $165,600
c. The total material cost for ending cost of goods sold would be
= 19,800 tons × $23
= $455,400
