In a lilac paint mixture, 40% of the mixture is white paint, 20% is blue, and the rest is red. There are 4 cups of blue paint used in a batch of lilac paint. How many cups of white paint are used? How many cups of red paint are used? How many cups of lilac paint will this batch yield?
40 % white 20% blue 40% red
Red and white amounts are equal....and each is twice as much as blue (40% vs 20%)
4 cups of blue means 8 cups of white and 8 cups of red total = 20 cups lilac
