Included in Sedans liabilities was an account payable to Pickup in the amount of $50,000, which Pickup included in its accounts receivable.

Based on the preceding information, what amount of total liabilities was reported in the consolidated balance sheet immediately after the acquisition?

answer is $820,000 ($370,000 + 300,000+ 200000 - 50,000)

Could you explain why we need to add 200,000 and minus 50000?
