Wayne  = (5/6)S.....so....

 

(5/6)S   - 28                       1

___________   =            ____                  cross-multiply

 S  -    28                          4 

 

 

4 ] (5/6)S   - 28 ]  =   S  -28

 

 

(10/3)S  -  112   =  S   - 28

 

(10/3)S  - S   =   112   - 28

 

(7/3)S  =  84

 

S  = (84)(3/7)   =  $36 = Stef's savings

 

Wayne  = (5/6)S =  (5/6)(36)  =  $30  = Wayne's savings
