 Example: I = \$184, T = 2 years and R = 2%, then find principle. Solution: Formula I = PTR/100 Where I = Interest, P = Principal, T = Time and R = Rate or interest. Therefore: P = (I*100) / (TR) Substituting the given values in the above formula. P = (184 * 100) / (2 * 2) P = 18400 / 4 P = \$4,600 Directions: Solve the following problems. Also write at least ten examples of your own.
