My Business Frat Wants To Take 25% Of The Money Meant For Charity. Is This Legal? (sc)

South Carolina My business frat held a fundraising event in the fall for the local food bank. The profit we made ~$3k (after costs we made that amount) The idea behind it was to raise money for thanksgiving meals. The image of the flyer I have says that it's to "raise funds" for the food bank. It doesn't say a portion of proceeds goes to charity or anything like that. We have a meeting this week to go over frat business and vote on some resolutions. They announced that not only have we not paid the food bank yet but that we need to decide on how much to give. Another person and I tried to argue that they should get the full amount but we were in the minority. Ultimately the resolution that was passed was for us to take what amounted to ~25% of the profit for ourselves to cover "future costs" like our upcoming induction ceremony. I think this is morally wrong. I've already requested a meeting with a member of faculty who is like an advisor for us to express this (who was in attendance along with another). But I want to know if this is even legal for them to do.
