[ 1/1Inequality]
    Assignment:Find the solution set of inequality [y－2×（1＋10%）]×7200×（1＋10%）-（3-2）×7200 ≥720 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( y - 2 × ( 1 + 10 % ) ) × 7200 × ( 1 + 10 % ) - ( 3 - 2 ) × 7200 ≥720         (1)

---

    From inequality(1)：
         y ≥ 16/5

---

    The final solution set is :
         y ≥ 16/5
