                  Final score = 85

                  Starting score = 74

           Equation (1) becomes,

                  Percentage of increase =( \frac{85-74}{74}) ×  100

                                                       = (\frac{11}{74}) ×  100

                                                       = 0.1486486  ×  100

                                                       = 14.86486 %

                                                      ≅ 14.87 %

              Percentage of increase = 14.87 %

Result:

        The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
