    Assignment:Find the solution set of inequality 364＋100×（1+20％）×（y－3）－640 ≥（90－5）y .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        364 + 100 × ( 1 + 20 % ) × ( y - 3 ) - 640 ≥ ( 90 - 5 ) * y         (1)

---

    From inequality(1)：
         y ≥ 18.171429

---

    The final solution set is :
         y ≥ 18.171429
