Oconnor · Answer 1

She used 4.9 pints of blue paint.

Explanation:

The total amount of paint that Melanie used is 9.4 pints (white and blue).

Blue Paint + White Paint = 9.4 pints.

However, we know that 4.5 of the total amount is white, thus, we can substitute in the expression we just wrote earlier:

Blue Paint + 4.5 = 9.4 pints

Blue Paint = 9.4 pints - 4.5 pints

Blue Paint = 4.9 pints.

Therefore, she used 4.9 pints of blue paint for her bedroom walls.
