Step-by-step explanation:
_______________________________________________________

(60,000) / (250) = "n" / (1,008,000) ;

Solve for "n" ; {number of cans used each year in Dallas} ;

(250) n = (60,000)(1,008,000) ;

Divide each side of the equation by "250" ;
to isolate "n" on one side of the equation; & to solve for "n" ;

→ { (250) n} / 250 = [ (60,000)(1,008,000) ] / 250 ;

to get:

→ n = (60,480,000,000) / (250) ;

→ n = 241,920,000
