Kelly runs a restaurant that sells two kinds of desserts. Kelly knows the restaurant must make at least 25 dozen and at most 45 dozen white chocolate blizzards. The restaurant must also make at least 2 dozen and at most 15 dozen mints breezes. Each dozen of white chocolate blizzards takes 5 ounces, of flour, while each dozen of mint breezes requires 9 ounces of flour. The restaurant only has 315 ounces of flour available. If a dozen white chocolate blizzards generate $2.92 in income, and a dozen mint breezes generate $2.11, how many dozens of the desserts should Kelly have the restaurant make to maximize income?
