 Question 626171: The capacity of an automobile cooling system is 16 quarts. It is half full of a 15% antifreeze solution. The owner is adding 2 gallons of a 90% solution (remember, 1 gallon = 4 quarts). When he is finished, what will the solution's percentage value be?Answer by josmiceli(9671)   (Show Source): You can put this solution on YOUR website! qts x gal/qt = gal The capacity is 4 gallons It is half full, so It has 2 gallons of 15% antifreeze gallons antifreeze in tank ----------------- The owner fills the tank by adding 2 gallons of 90% antifreeze gallons of antifreeze The total antifreeze in tank is then gal The solution's percentage will be 52.5%
