Instructions are below.

Explanation:

Giving the following information:

Production= 400 units

direct materials= $14 per unit

direct labor= $27 per unit

variable manufacturing overhead= $10 per unit

total fixed manufacturing overhead costs= $4,000

variable selling and administrative costs=  $9 per unit

total fixed selling and administrative costs= $3,200

The difference between the absorption costing and variable costing methods is that the last one includes the fixed manufacturing costs in the unitary product costs.  

1) Absorption costing:

Unitary fixed overhead= 4,000/400= $10

Unitary product cost= 14 + 27 + (10 + 1)= $61

2) Variable costing:

Unit product cost= 14 + 27 + 10= $51

3) Absorption costing:

Sales= 1,800*100= 180,000

COGS= (61*1,800)= (109,800)

Gross profit= 70,200

Total selling and administrative costs= 3,200+ (9*1,800)= (19,400)

Net operating income= $50,800

4) Variable costing:

Sales= (1,900*100)= 190,000

Total variable cost= (60*1,900)= (114,000)

Contribution margin= 76,000

Fixed selling and administrative costs= (3,200)

total fixed manufacturing overhead costs= (4,000)

Net operating income= 68,800
