Final answer:
The Variable Income Statement can be used in all options except for when the CFO is submitting financial information to the IRS for a yearly audit.
Step-by-step explanation:
The Variable Income Statement can be used in all of the options except c. CFO is submitting financial information to the IRS for yearly audit.
A Variable Income Statement is a type of financial statement that displays the revenues, costs, and expenses that vary with changes in sales volume or production level. It provides information on the profitability of specific products or divisions of a company.
In option c, the CFO is submitting financial information to the IRS for a yearly audit. This is not related to the use of a Variable Income Statement to make business decisions. The IRS audit is focused on compliance with tax regulations, rather than operational decision-making.
The other options, a. For the CEO who is deciding to expand the production of a certain product, b. A supervisor who is deciding to take a special order, and d. The new manager is assigned with lowering cost in its regular production, all involve making business decisions based on the information provided by a Variable Income Statement.
