Answer:
Expenditures $300,000; Supplies inventory $150,000.
Step-by-step explanation:
The consumption method recognizes an asset when an item is purchased and an expense when an item is used or consumed. Therefore, when supplies are first bought, Supplies Inventory has a balance of $450,000.
After using those supplies during the year, $300,000 should be debited from Supplies Inventory and credited to Expenditures.
Therefore, at fiscal year-end, the appropriate account balances on the General Fund financial statements would be: Expenditures $300,000; Supplies inventory $150,000.
