How many quarts of water must be added to 4 quarts of an 80 percent mixture to obtain a 50 percent mixture?
To find out how many quarts of water must be added, we first calculate the amount of pure substance in the 80 percent mixture. In 4 quarts of an 80 percent mixture, there are 3.2 quarts of the substance (0.8 x 4). Let ( x ) be the amount of water added. The total volume after adding water will be ( 4 + x ) quarts, and we want this to equal a 50 percent concentration, which gives the equation ( 3.2 = 0.5(4 + x) ). Solving for ( x ) gives ( 3.2 = 2 + 0.5x ), resulting in ( 0.5x = 1.2 ), or ( x = 2.4 ). Therefore, 2.4 quarts of water must be added.

A car's radiator has a capacity of 15 quarts and it currently contains 12 quarts of a 30 percent antifreeze solution. How many quarts of pure antifreeze must be added to strengthen the solution 40 per?
The original solution has 3.6 quarts of antifreeze in it. The equation then becomes (3.6 + x)/(12 + x) = 0.40, where x is the amount of antifreeze added. X is then equal to 2.
