To help Sean understand how his loan details are calculated, write a brief explanatory memo that addresses the following:
- State the standard simple interest formula and recall the definition of each variable (, , , ) in the formula.
- Identify the specific numerical values given in Sean's statement, match them to the correct variables, and state which variable represents the unknown quantity we need to find.
- Recall and outline the step-by-step problem-solving strategy to translate these values into an equation, solve for the unknown principal, and verify the accuracy of the final calculation.
