put this solution on YOUR website!I'm assuming it's not that you need 574 points, but rather that's the most you could have gotten (if you had 574, you would have 100%). So, you have 493.5 out of a possible 574. We find your percentage by dividing your points by the total possible, and multiplying by 100. So, we divide to get 0.859756, and multiplying by 100 gives 85.98%.
