For each of the following statements, select
True if the statement can be verified to be true based on the information provided. Otherwise, select
False.
Statement 1: Profit = Revenue * Profit Margin. Observe that we don’t need to calculate the profit for all companies in all years. By quickly glancing through the numbers, we can identify which companies could potentially have the highest profit based on their high revenue and high profit margin. This allows us to save time by focusing only on the most likely candidates.
In this case, Company C and Company E stand out as having both high revenue and high profit margins. Calculating these confirms that E had the highest profits in all three years. Thus, this statement is True.
Statement 2: To evaluate this statement, check Company C's profit margin trends over the three years:
2021: 15% → 2022: 14% → 2023: 13%.
