[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2190*（x/10）+3650*1*0.4 ≤2190+219+3650*0.55*0.4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2190 * ( x / 10 ) + 3650 * 1 * 0.4 ≤2190 + 219 + 3650 * 0.55 * 0.4         (1)

---

    From inequality(1)：
         x ≤ 8

---

    The final solution set is :
         x ≤ 8
