Step-by-step explanation:
The computations are shown below:
a. Under the absorption costing method, the average unit product cost is
= (Direct materials cost + Direct labor cost + Variable overhead cost + Fixed overhead cost) ÷ (Number of unit produced)
= ($223,000 + $182,000 + $42,000 + $157,000) ÷ (26,600 units)
= $22.71
Now the product cost would be
= 21,700 units × $22.71
= $492,807
b. Under the variable costing method, the average unit product cost is
= (Direct materials cost + Direct labor cost + Variable overhead cost) ÷ (Number of unit produced)
= ($223,000 + $182,000 + $42,000) ÷ (26,600 units)
= $16.80
Now the product cost would be
= 21,700 units × $16.80
= $364,560
