a statue is being carved by a sculptor . the original piece of marble weighed 200 kg . in the first week 20 percent is cut away . in the second week 25 percent of the remainder is cut away . in the third week the statue is completed when 35 percent of the remainder is cut away . what is the weight of the final statue ?
"a 97.5 kg 250 ã — 0.8 ã — 0.75 ã — 0.65 = 97.5 kg ."
multiply(subtract(const_1, divide(35, const_100)), multiply(subtract(const_1, divide(25, const_100)), multiply(200, subtract(const_1, divide(20, const_100)))))
