According to the given graph, 2 cups of white paint are in the same ratio as 6 tablespoons of blue paint.
So, if she has 6 cups of white paint, we just have to multiply the number of tablespoons by 3.

So, Elena needs 18 tablespoons of blue paint.
Additionally, this would make three batches because the given ratio is being multiplied by 3.
