Answer:
18 tablespoons of blue paint; 3 batches
Explanation:
For 1 batch of paint, she uses 2 cups of white paint and 6 tablespoons of blue paint.
She needs to mix blue paint using 6 cups of white paint.
6 cups is 3 times 2 cups, so she will be making 3 batches.
She also needs to use 3 times the amount of blue paint that she would use for 1 batch.
Since she uses 6 tablespoons of blue paint in 1 batch, she needs to use 3 times as much blue paint.
3 * 6 tablespoons = 18 tablespoons.
