Last year, Stephen Company had 20,000 units in its ending inventory.

unit. The fixed manufacturing overhead cost was $8 per unit in the
beginning inventory. The company's net income for the year was $9,600
higher under variable costing than it was under absorption costing.

inventory last year must have been:

b. 19,200.
c. 18,800.
d. 19,520
