Answer:
Results are below.
Explanation:
The absorption costing method includes all costs related to production, both fixed and variable. The unit product cost is calculated using direct material, direct labor, and total unitary manufacturing overhead.
The variable costing method incorporates all variable production costs (direct material, direct labor, and variable overhead).
a) First, we need to calculate the unitary production cost under absorption costing:
Unitary production cost= (575,000 / 50,000) + (80,000 / 50,000)
Unitary production cost= $13.1
Now, the absorption costing income statement:
Sales= 42,000*18= 756,000
COGS= 13.1*42,000= (550,200)
Gross profit= 205,800
Total Selling and administrative expenses= (45,500)
Net operating income= 160,300
b) First, we need to calculate the total unitary variable cost:
Total unitary variable cost= (575,000/50,000) + (35,000 / 42,000)
Total unitary variable cost= $12.33
Now, the income statement:
Sales= 756,000
Total variable cost= 12.33*42,000= (517,860)
Total contribution margin= 238,140
Fixed overhead= (80,000)
Fixed selling and administrative= (10,500)
Net operating income= 147,640
