Opening inventory was 500 units and closing inventory was 1,800 units. Under marginal costing profit was $84,000. Fixed production overhead was absorbed at $8 per unit under absorption costing, with the rate unchanged between opening and closing inventory. What was the absorption costing profit?

Absorption costing profit is $94,400. Inventory rose by 1,300 units (1,800 less 500), so 1,300 x $8 = $10,400 of fixed overhead is carried forward under absorption costing. Adding this to the marginal costing profit of $84,000 gives $94,400.

  2. B$73,600
  3. C$98,400
  4. D$69,600

Explanation

Inventory increased by 1,800 - 500 = 1,300 units. Fixed overhead deferred in inventory = 1,300 x $8 = $10,400. Absorption profit = $84,000 + $10,400 = $94,400. Option B subtracts instead of adding. Option C uses closing inventory only (1,800 x $8 = $14,400 gives $98,400).
