Question

There must be some missing information here. The reason I say this is that your statement "24000 liters of energy drink must be used" implies that you need to have that much energy drink. But, if each can uses 1.25kg of powder, (do you see where the problem is, it isn't clear what uses 1.25kg of powder, is it a can or is it the 24,000 L of energy drink? Furthermore, how many L is in each can of the energy drinks? How can one determine the number of cans if you don't know the volume of each can?)

I'll be happy to show you how to work this problem but it needs to be more clearly stated.
