if leo gains 10 pounds , he will weigh 50 % more than his sister kendra . currently their combined weight is 160 pounds . what is leo ' s current weight ?
"l + k = 160 and so k = 160 - l l + 10 = 1.5 k = 1.5 ( 160 - l ) 2.5 l = 230 l = 92 the answer is c ."
divide(subtract(multiply(160, divide(add(const_100, 50), const_100)), 10), add(divide(add(const_100, 50), const_100), const_1))
