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?
+37157 In the initial 20 quarts of mixed paint there is 25% red sooooo 20 qrts * .25 = 5 quarts of red
now add 4 quarts of red now there is 9 quarts of red in 20 + 4 quarts
9/24 * 100% = 37.5% red
