Final answer:
The sale of the plant assets should be shown on Hager's statement of cash flows (indirect method) as a subtraction from net income of $30,000 and a $90,000 increase in cash flows from investing activities. The gain from the sale is a non-operating item that represents a cash inflow from the investment activities of the company.
Step-by-step explanation:
In this case, the sale of the plant assets should be shown on Hager's statement of cash flows (indirect method) as a subtraction from net income of $30,000 and a $90,000 increase in cash flows from investing activities.
When a company sells its plant assets, it needs to account for the gain or loss on the sale. In this case, the original cost of the plant assets was $900,000, and the accumulated depreciation was $840,000. Therefore, the carrying amount of the assets was $60,000 ($900,000 - $840,000).
Since the proceeds from the sale were $90,000, there was a gain of $30,000 ($90,000 - $60,000). This gain is subtracted from net income because it is a non-operating item, and it represents a cash inflow from the investment activities of the company.
