There is weight limit to the bag so that it won't break. It means the weigh of all the candies should not exceed a particular value.
Let x pound of candy is removed from each bag afer filling 2.5 pounds in it.
The amount of candy left in each bag will be 2.5-x.
The weight of all the 12 small pastic bags will be 12(2.5-x).
The total weight should not exceed a particular limit each bag can not exceed a particular limit, hence the required inequality can be,
Thus, option (C) is the correct solution.
