Answer:
Cost of Goods Sold or Equity Account Dr. $11.8
Inventory Cr. $11.8
Step-by-step explanation:
Under FIFO method inventory was overvalued by $11.8 which needs to adjusted by lowering the inventory by $11.8. The corresponding effect of overvalued inventory was reflected in income statement which ultimately became part of equity 9equity increased as result of this) which also needs to adjusted by debiting the equity/cost of goods sold.
This change from FIFO to average cost is called change of accounting policy which is retrospectively accounted for.
