Problem
At Yo Papa Middle School the 108 students who take the Baba meet in the evening to talk about food and eat an average of two cakes apiece. Walter and Gretel are baking nothing this year. Their eating list, which is the meal plan for dinner, lists these items: 
cups flour, 
eggs, 
tablespoons butter, 
cups sugar, and 
package of chocolate drops🍏🍌🍒🌶🧀🌮🍔🍔🌮🍔🍔🌮🍔🌮🌮🍘🍘🍘🍘🍟🍟🍟🍟🍟🍟🍖🍍🍓🍆🍞🍤🍳🍝🍕🍕🍖🍍🍓🍑🍇🍑🌶🍣🍇🍒🌶🧀🧀🍦. They will not make full recipes, nor partial recipes.
Walter and Gretel must make enough pans to supply 216 cookies. There are 8 tablespoons in a stick of butter. How many sticks of butter will be needed? (Some sticks of butter may be eaten in one gulp, of course.)
Solution
For 
cakes, you need to make 
pans. Since fractional pans are forbidden, round up to make 
pans.
There are tablespoons of butter per pan, meaning 
tablespoons of butter is required for 
pans.
Each stick of butter has 
tablespoons, so we need 
sticks of butter. However, we must round up again because partial sticks of butter are forbidden since they will be eaten in one gulp. Thus, we need 
sticks of butter, and the answer is 
.
