A shade of purple paint is made with 4 ounces of red paint, 5 ounces of blue paint, and 2 ounces of white paint
How many ounces of blue paint are needed to make an 88-ounce batch of purple paint?
the answer would be 40 ounces of blue paint. all together the paint makes 11 ounces and you need 88. 11x8=88 so take 5 and multiply it by 8 to get 40. correct me if i'm wrong :)
