In the formula \( A = (1 + RT/100) \), the variables represent the following:
-
\( A \): This is the total amount of money accumulated after interest is applied, including both the principal and the interest earned.
-
\( R \): This stands for the annual interest rate (expressed as a percentage).
-
\( T \): This represents the time period for which the money is invested or borrowed, typically measured in years.
-
\( 100 \): This is a constant that converts the interest rate from a percentage into a decimal for calculation purposes.
The formula itself is typically used in the context of simple interest calculations, where interest is calculated only on the initial principal over a specified period.
