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. If you get stuck, consider using a tape diagram. 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?

White paint and Red paint = 8 cups and the Whole Batch= 20 cups

Step-by-step explanation:

Ok the white paint is 40% and the blue paint is 20%. Add these together and you get 60%, which means that the other 40% is red paint.

White paint= 40%

Blue paint = 20% (4 cups)

Red paint = 40%

If we look at the blue paint, multiplying that by 2 will make it 40%. This means that the While paint and Red paint both equal 8 cups.

White paint = 8 cups

Blue paint = 4 cups

Red paint = 8 cups.

This comes out to 20 cups of paint. Check with a calculator just to make sure. Hope this helps!
