a statue is being carved by a sculptor . the original piece of marble weighed 300 kg . in the first week 30 percent is cut away . in the second week 30 percent of the remainder is cut away . in the third week the statue is completed when 15 percent of the remainder is cut away . what is the weight of the final statue ?
"d 125 kg 300 ã — 0.7 ã — 0.7 ã — 0.85 = 125 kg ."
multiply(subtract(const_1, divide(15, const_100)), multiply(subtract(const_1, divide(30, const_100)), multiply(300, subtract(const_1, divide(30, const_100)))))
