When a bookkeeper uses the US dollar as currency and ignores changes in its value, this is known as the Monetary Unit Assumption.

• A. Going Concern Assumption
• B. Monetary Unit Assumption
• C. Collaboration Assumption
• D. Consistency Assumption

Answer: (B)

The main idea being tested is that financial statements are measured in a single currency and changes in that currency’s purchasing power are not adjusted in the numbers. The Monetary Unit Assumption says exactly this: use the US dollar (or the entity’s currency) as the unit of measure and ignore inflation or deflation effects on the currency when reporting amounts. This keeps measurements consistent and comparable over time without revaluing every item for changes in value. In this scenario, using the US dollar as the currency and not reflecting changes in its value aligns with that principle. Other options describe different accounting ideas—such as continuing operations as a business assumption or maintaining the same methods from period to period—so they don’t fit this description.
