_________________________________________

3:5::x:520,000 ?  

Solve for "x" (Note: "x" is in dollars);

3/5 = x/520,000  ;

Using "cross-factor multiplication" ;
__________________________________________________
   5x = (3)*(520,000) ;
__________________________________________________
   Divide each side by "5" ; to isolate "x" on one side of the equation; and to solve for "x":
__________________________________________________
   →  $\frac{5x}{5}$  =   [tex] \frac{3 * 520,000}{5} ;   
_______________________________________________
  Note:  "520,000 ÷ 5 = 104,000" ; 
_______________________________________________
 Rewrite as:
______________________________________________
                       → x = 3 * 104,000  ;
 
                       → x = 312,000 dollars;

The answer is:  $ 312,000 .
