Depends on the people. If teenagers, about a package each

5 pounds of macaroni should be enough to feed 20 people. Depending on appetite each pound can feed between 4 and 5 people.
How much macaroni and cheese do I need to feed 200 people for one meal
To make a large cheesy potatoe casserole for 150 people I would use between 50 and 60 pounds of potatoes which would be about 180 individual potatoes or five to six ten pound bags of potatoes.
Kraft Macaroni and Cheese is a boxed dinner that comes with a powdered cheese packets and raw macaroni. At Walmart, a single box of Kraft Mac and Cheese sells for a little less than 1 USD.
If all 210 people are eating exactly 1 serving, it will cost around 6,930 cents or $69.
I doubt that very much. For one thing why would the makers waste that money.
I don't think so but, Kraft Mac and Cheese has different size boxes.
For 200 people, you'd need around 3 gallons of macaroni salad.
I think 4 ounces is enough as a side. That would mean about 38 pounds of mac'n cheese.
About 25 cups
I would make 12 pounds IF it is a side dish, or about 35 pounds if it is the main dish.
