Answer:
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!
