Tony saves 1344/12   =  $112  per month more than Kurt

 

So....let x be the monthly salary for both

 

So

 

(9/11) x   =   (7/9)x   +  112            multiply through by  99

 

81x  = 77x  + 11088     subtract  77x  from both sides

 

4x  = 11088      divide both sides by  4

 

x  = $2772   = monthly salary for both

 

 

cool cool cool
