What is the formula for calculating % absorption?

• A. [(A+B)/A] x 100
• B. [(B-A)/A] x 100
• C. [(A-B)/B] x 100
• D. [A*(B-A)] x 100

Answer: (B)

The formula for calculating % absorption is represented as [(B-A)/A] x 100. This formula effectively quantifies the percentage change between two values, A and B, where A represents the initial value and B represents the final value after absorption has taken place.

By subtracting A from B, you determine the amount of absorption that has occurred. This difference is then divided by the initial value (A), providing a ratio of the absorption relative to the starting point. Multiplying this ratio by 100 converts it into a percentage, which is a common method for expressing changes in various fields, including statistics and finance.

Understanding this formula is crucial for interpreting changes effectively, especially when analyzing data related to absorption rates in various contexts. The other formulas provided do not accurately represent the concept of absorption as they either confuse the variables involved or do not provide a percentage change calculation.
