The answer is:
$ 312,000 .
___________________________________________Step-by-step explanation:_________________________________________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":
__________________________________________________ →

= [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 .
