This math topic focuses on the manipulation of the simple interest formula \( I = PRT \) to solve for different variables such as Time (T), Principal (P), and Rate (R). It provides exercises that require the learner to rearrange the formula, thereby enhancing their understanding of algebraic manipulation in the context of solving real-world financial problems related to simple interest. This practice is part of a larger unit on Percents and Simple Interest. Each problem poses a question regarding how to isolate a specific variable in the formula, with multiple-choice answers presenting different algebraic rearrangements.
