Answer: 
b) $113,000 
Explanation: 
For the computation of net income under absorption costing first we need to follow some steps which is shown below:- 
variable overhead per unit = $105,000 ÷ 35,000 
= $3 per unit 
The Variable cost of production per unit 
Particulars Amount 
Direct material $19.00 
Direct labor $21.00 
Variable overhead $3.00 
Variable cost of production 
per unit $43.00 
Cost per unit of finished goods under absorption costing 
Particulars Amount 
Total direct material cost $665,000 
($19 × 35000) 
Total direct labor $735,000 
($21 × 35000) 
Total variable overhead $105,000 
Total fixed overhead $175,000 
Total $1,680,000 
Units in finished goods = Number of units produced - units sold 
= 35,000 - 21,000 
= 14,000 
Cost of finished goods under variable costing 
= Variable cost of production per unit × Number of units in finished goods 
= $43 × 14,000 
= $602,000 
Cost of goods sold 
= Production cost - Finished goods cost 
 = $1,680,000 - $602,000 
= $1,078,000 
 Income statement under absorption costing 
Particulars Amount 
Sales revenue $1,491,000 
($71 × 21,000) 
Less: cost of goods sold -$1,078,000 
Gross Profit $413,000 
Less : operating expenses -$300,000 
Net operating income $113,000
