문제

At Central Middle School, the 108 students who take the AMC 8 meet in the evening to talk about food and eat an average of two cookies apiece. Hansel and Gretel are baking Bonnie's Best Bar Cookies this year. Their recipe, which makes a pan of 15 cookies, lists these items: 1121\frac{1}{2} cups flour, 22 eggs, 33 tablespoons butter, 34\frac{3}{4} cups sugar, and 11 package of chocolate drops. They will make full recipes, not partial recipes.

Hansel and Gretel must make enough pans of cookies to supply 216 cookies. There are 8 tablespoons in a stick of butter. How many sticks of butter will be needed? (Some butter may be leftover, of course.)
