a broker invested her own money in the stock market . during the first year , she increased her stock market wealth by 60 percent . in the second year , largely as a result of a slump in the stock market , she suffered a 30 percent decrease in the value of her stock investments . what was the net increase or decrease on her overall stock investment wealth by the end of the second year ?
the actual answer is obtained by multiplying 160 % by 70 % and subtracting 100 % from this total . that is : 160 % × 70 % = 112 % ; 112 % − 100 % = 12 % . answer : c
multiply(subtract(multiply(add(const_1, divide(60, const_100)), subtract(const_1, divide(30, const_100))), const_1), const_100)
