Given the Balance Sheets for XYZ Company above for the years ending December 31, 2007 and 2008, find Net Cash Flows from Operating Activities for 2008 assuming the following income statement data:
Net income (2008) = $3,644 and Depreciation (2008) = $903

Here's my answer to Net Cash Flows from operating but I want to know if it's right or not.

Diff changes accounts receivable, inventory, accounts payable and accruals

-400 +500 -1,000 +400 -500
Net income + depreciation 3,644 + 903 = 4,547

Answer: 4,547-500 = 4047

Your adjustments are all out of order, so I don't know what is what. Either keep them order of current assets and then current liabilities or write on them what they are. And you seemed to have skipped receivables altogether.
