if leo gains 10 pounds , he will weigh 50 % more than his sister kendra . currently their combined weight is 180 pounds . what is leo ' s current weight ?
l + k = 180 and so k = 180 - l l + 10 = 1.5 k = 1.5 ( 180 - l ) 2.5 l = 260 l = 104 the answer is e .
divide(subtract(multiply(180, divide(add(const_100, 50), const_100)), 10), add(divide(add(const_100, 50), const_100), const_1))
