[ 1/1Inequality]
    Assignment:Find the solution set of inequality （x+800-2500-5213.15-4455.78）*（1-0.25）/（100000*0.3*0.9） ≥0.12 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x + 800 - 2500 - 5213.15 - 4455.78 ) * ( 1 - 0.25 ) / ( 100000 * 0.3 * 0.9 ) ≥0.12         (1)

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
