Answer:
Liabilities at the end of the year were: $15,000.
Step-by-step explanation:
Using the Accounting Equation : Assets = Equity + Liability
Then we know that,
Liability = Assets - Equity
Opening Balance of Liabilities ( $30,000 - $20,000) = $10,000
Adjustment during the year ($20,000 - ($45,000 - $30,000)) = $5,000
Ending Balance of Liability = $15,000
