Answer:
($3,000)
An outflow
Explanation:
The cash flow statement categories the company's transactions in a financial period into 3 groups; these are operating, investing and financing.
The net profit/loss, depreciation, changes in current assets (other than cash) and liabilities are considered as operating activities including income taxes.
In cash flow statements, an increase in assets(other than cash) is treated as a cash outflow while a decrease is considered as an inflow of cash.
Hence if accounts receivables balance increases from $45,000 i 2018 to $48,000 in 2019, the change of $3,000 will be shown as an outflow.
