    Assignment:Find the solution set of inequality 4/5(380－x)+x ≤400×85% .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4 / 5 * ( 380 - x ) + x ≤400 × 85 %         (1)

---

    From inequality(1)：
         x ≤ 180

---

    The final solution set is :
         x ≤ 180
