    Answer: Hello mate!

    We know that Xavier spent $84 on art supplies. For each painting, he spends $1 on the canvas and sells each paint for $8.

    The proffit equation is:

    Q (p) = ($8 - $1) p - $84 = $7p - $84

    where p is the number of paintings that he sells.

    If we want to obtain the number of paintings that he needs to sell in order to break even, we need to calculate:

    Q (p) = 0 = $7p - $84

    $7p = $84

    p = 84/7 = 12

    He needs to sell 12 paints to break even.
