Problem: $ 350 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 ?
Rationale: "let the shares for a , b , and c be x , 2 x , and 4 x respectively . 7 x = 350 x = 50 4 x = 200 the answer is c ."
annotated_formula: multiply(divide(350, add(add(divide(const_1, const_2), const_1), const_2)), const_2)
