[ 1/1Inequality]
    Assignment:Find the solution set of inequality 【13（1+0.7x）-10(1+x)】*5000(1+0.4x) >15000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 13 * ( 1 + 0.7 * x ) - 10 * ( 1 + x ) ) * 5000 * ( 1 + 0.4 * x ) >15000         (1)

---

    From inequality(1)：
         0 < x < 5/6

---

    The final solution set is :
         0 < x < 5/6
