The correct answer is B. -$280,000 . To determine cash flow from investing activities , include only cash flows related to the acquisition and disposal of long-term assets and investments. In the transactions listed, the only investing activity is:

Property and equipment purchase = -$280,000

That makes total cash flow from investing activities -$280,000 . OpenStax states that the investing section of the statement of cash flows relates to changes in long-term assets, and FASB’s cash flow guidance classifies acquisitions of productive assets as investing cash outflows.

The other listed items belong to different sections. Sales, inventory purchases, wages, rent, and interest payments are generally operating activities under U.S. GAAP. Borrowing long-term debt, paying dividends, and repurchasing treasury stock are financing activities . Since none of those belong in investing activities, they should not be included in the investing subtotal. Therefore, the total cash flow from investing activities is simply the cash paid for property and equipment, which is -$280,000 , making Option B the correct answer.
