Above are links the to the Fraction Project for Mr. Ehlers math class and Mr. Schwiebert's math class. Remember you are cooking for 200 people. You will need to adjust the recipe to make sure it will feed 200 people. Oh yeah, you have several recipe's to choose from BUT, you will need to figure out what recipe you can create for the cheapest price. Enjoy, have fun, and I hope you are hungry.
