You can put this solution on YOUR website!
So you want to remove v gallons of the low concentration mixture of antifreeze and replace it with v gallons of the pure 100% antifreeze. You want the finished volume to be the same as before. The current concentration as percent in the tank is \"p%5Bb%5D\" and you want a finished concentration\"+p%5Bt%5D\".\r
