It sounds like you're providing information about a popcorn machine at a movie theater. If Theater A has a popcorn machine with a 100-gallon capacity, this could be relevant for several purposes, such as calculating how much popcorn can be made for screenings, determining how often the machine needs to be refilled, or planning for special events.
If you'd like more specific information or have a particular question related to this, such as conversions to other units, a comparison with another theater, or efficiency considerations, please let me know!
