There are several information's already given in the question. Based on those information's, the answer can be easily deduced.

Cost of the jacket = $124.99
Percentage of discount given at the beginning = 10%
Amount of initial discount given = (10/100) * 124.99
                                                   = 12.499 dollars
                                                   = 12.50 dollars
Then
Price of the jacket after the initial discount = 124.99 - 12.50
                                                                   = 112.49 dollars
Percentage of additional discount = 20%
Amount of additional discount = (20/100) * 112.49
                                                = 22.50 dollars
Total amount saved on buying the jacket = 12.50 + 22.50
                                                                  = 35 dollars
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
