Sunny · Answer 2

She needs 4 more gallons of blue paint than red paint

Step-by-step explanation:

Since the ratio is 3 to 2, 3 + 2 = 5.

The artist needs 20 gallons of purple paint, so 20/5 = 4

The amount of blue and red paint needed is 4x3 to 4x2, or 12 to 8.

She needs 12 gallons of blue paint and 8 gallons of red paint.

12 - 8 = 4

She needs 4 more gallons of blue paint than red paint.
