Answer:
44 kg.
Explanation:
The weight limit of the luggage = 33 kg
Let the original weight of the suitcase = x kg
Now, it has been given that Carl has to lower the weight of his suitcase by 25% to stay within the limit.
It means that if we decrease the original weight of the suitcase by 25% then it should be equal to 33 kg.
Thus, we have the equation

Solve the equation

Therefore, the original weight of the suitcase was 44 kg.
