A mixture is 25% red paint, 30% yellow paint, and 45%water. If 4 quarts of red paint are added to 20 quarts of the mixture, what is the percentage of red paint in the new mixture?

How much red is in the original 20 quarts ?      .25 (20) = 5 quarts

    now add 4 more quarts for a total of 9 quarts in a total of   24 quarts       9/24 * 100% = 37.5 % red
