1. The divisional manager has decided to increase the advertising budget by $300,000. This will increase sales revenues by $3 million. By how much will operating income increase or decrease as a result of this action?
2. Suppose sales revenues exceed the estimated amount on the income statement by $945,000. Without preparing a new income statement, by how much are profits underestimated?
3. CONCEPTUAL CONNECTIONWhy can we take the shortcut of simply focusing on the increased sales revenue to determine increased profitability?
4. Determine the margin of safety based on the original income statement.
