if 42.18 = k ( 14 + m / 50 ) , where k and m are positive integers and m < 50 , then what is the value of k + m ?
"42.18 = 14 k + km / 50 . . . we can rewrite the number as follows : 42 + 0.18 = 14 k + km / 50 . . . . . . . . since k is integer , then 42 = 14 k . . . . . . . . . . k = 3 0.18 = km / 50 . . . . . . 18 / 100 = 3 m / 50 . . . . . . m = 3 k + m = 3 + 3 = 6 answer : a"
add(divide(multiply(subtract(const_0_25, divide(const_1, const_100)), 50), divide(subtract(42.18, subtract(const_0_25, divide(const_1, const_100))), 14)), divide(subtract(42.18, subtract(const_0_25, divide(const_1, const_100))), 14))
