Sales Volume                     2,700                  1,730             4,430
Sales per unit                    $10.70                $23.70             -
Sales Revenue               $28,890              $41,001           $69,891

Net operating income                                                       $34,317
Therefore, operating cash flow = net operating income after tax + depreciation
operating cash flow = $34,317 × (1 - 0.40) + ($1,000 × 0.40)
Hence, operating cash flow = $20,590 + 400 = $20,990
