[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1-e^(-(5000-k)*0.85^k*0.15-0.85^k) >0.99 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 - e ^ ( -( 5000 - k ) * 0.85 ^ k * 0.15 - 0.85 ^ k ) >0.99         (1)

---

    From inequality(1)：
         k < √980117939/1000

---

    The final solution set is :
         k < √980117939/1000
