    Assignment:Find the solution set of inequality 20x+25x+20*70%（150-x）+15（200-x）-4800 ≥2348 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20 * x + 25 * x + 20 * 70 % * ( 150 - x ) + 15 * ( 200 - x ) - 4800 ≥2348         (1)

---

    From inequality(1)：
         x ≥ 128

---

    The final solution set is :
         x ≥ 128
