percent increase : (new number - original number) / original number...* 100
                            : (3.40 - 2.30) / 2.30.....* 100
                            : 1.1 / 2.30....* 100
                            : 0.4783 * 100
                            : 47.83 % increase....not sure if u need it to the nearest                                       percent or not, if so, it is 48%
