exactly 18 % of the reporters for a certain wire service cover local politics in country x . if 40 % of the reporters who cover politics for the wire service do not cover local politics in country x , what percent of the reporters for the wire service do not cover politics ?
"let ' s assume there are 100 reporters - - > 18 reporters cover local politics . now , as 40 % of the reporters who cover all politics do not cover local politics then the rest 60 % of the reporters who cover politics do cover local politics , so if there are x reporters who cover politics then 60 % of them equal to 18 ( # of reporters who cover local politics ) : 0.6 x = 18 - - > x = 30 , hence 30 reporters cover politics and the rest 100 - 30 = 70 reporters do not cover politics at all . answer : d ."
multiply(subtract(const_1, divide(18, subtract(const_100, 40))), const_100)
