[ 1/1Inequality]
    Assignment:Find the solution set of inequality 5.5y+((1-(1/60+1/90)y)/(1/90)*2) <= 186 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        5.5 * y + ( ( 1 - ( 1 / 60 + 1 / 90 ) * y ) / ( 1 / 90 ) * 2 ) <= 186         (1)

---

    From inequality(1)：
         y ≤ 370/11

---

    The final solution set is :
         y ≤ 370/11
