How much pork n beans should you buy to feed 75 people?

To feed 75 people, you should plan for about 1/2 to 1 cup of pork and beans per person, depending on whether it's a main dish or a side. This translates to approximately 37.5 to 75 cups of pork and beans in total. Since there are about 15 cups in a standard 3-pound can, you'll need around 3 to 5 cans to accommodate everyone. Adjust the quantity based on your guests' appetites and whether other dishes are being served.
