consider the amount of yellow paint.
If x liters of pure yellow are added, we need
.65 * 2/5 + x = .75(2/5 + x)
so now just solve for x
While mixing a light green paint, Luke mixes 35% blue paint and the rest is yellow. The green paint fills up two fifths of a litre container. Still thinking it needs to be a lighter green how much more yellow paint must be added to make the yellow paint 75% of the green paint?
