 Example: P = \$27,600, I = \$2484 and R = 3%, then find the time. Solution: Formula I = PTR/100 Where I = Interest, P = Principal, T = Time and R = Rate or interest. Therefore: T = (I*100)/(PR) Substituting the given values in the above formula. T = (2484 * 100) / (27600 * 3) T = 248400 / 82800 T = 3 years. Directions: Solve the following problems. Also write at least ten examples of your own.
