$ 406 is divided among a , b , and c so that a receives half as much as b , and b receives half as much as c . how much money is c ' s share ?
let the shares for a , b , and c be x , 2 x , and 4 x respectively . 7 x = 406 x = 58 4 x = 232 the answer is d .
multiply(divide(406, add(add(divide(const_1, const_2), const_1), const_2)), const_2)
