The volume of water in a tank, in liters, $m$ minutes after a drain is opened is modeled by the equation $V (m) = K - 10 m$ . $V (m)$ represents the volume at time $m$ , and $K$ represents the initial volume before draining began. If the tank contained 500 liters of water when the drain was opened (at $m = 0$ ), what is the value of $K$ ?
