Problema Solution
From 13.0 L of coolant containing 13.4% antifreeze, 5.50 L are removed. If 5.50 L of antifreeze are then added, how much antifreeze will be contained in the final mixture?

Assuming we need to find the percent antifreeze in the adjusted solution we have:
(0.134(13 - 5.50) + 5.50)/13 = 0.5004 or 50.04% antifreeze.
