    Assignment:Find the solution set of inequality (2000×12-8000)x+(4500×3-5000)(8-x) ≥100000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2000 × 12 - 8000 ) * x + ( 4500 × 3 - 5000 ) * ( 8 - x ) ≥100000         (1)

---

    From inequality(1)：
         x ≥ 64/15

---

    The final solution set is :
         x ≥ 64/15
