Answer:  " 
$ 165, 000 " .
___________________________________________________Explanation:___________________________________________________One method is to use "dimensional analysis" — as follows:
{ <u>Note</u>:  The " ( 

 }" ; as follows below —
             → refers to the "
30 hours per worker" 
— in a  "1 week period " ;    
             →  {as specified in this very question/problem} ; and as follows:
__________________________________________________
  →
  
 ;
 <u>Note:</u>  The following "units" get "canceled out to "1" ; and/or "eliminated" ;   
        → The "hr" {"hours"} units get canceled out / eliminately completely; 
                →   {since:  "hr / hr" =  " 1 " .} .
        →  The "worker(s)" units get canceled out/ eliminated completely; 
                →   {since:  "worker(s) / worker(s)" = " 1 " .} . 
______________________________________________________     →  We are left with:  " $ ( 5.5 * 30 * 1000 ) "  ;      
→   " $ ( 5.5 * 30 * 1000 ) "  ;
___________________________________________________       →   " $ ( 5.5 * 30 * 1000 ) "  ;                        
 =     " $ 165, 000 "  .
