[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.5a+(3600-50a)/100*1.2 <400000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.5 * a + ( 3600 - 50 * a ) / 100 * 1.2 <400000         (1)

---

    From inequality(1)：
         a ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    The final solution set is :
         a ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
