A bake sale can help raise money for a certain cause such as buying new library books for a school. If you are making muffins for a bake sale, you need a system to figure out how many batches you can make and how many muffins are in each batch. When you sell the muffins, you must figure out how much profit you make by subtracting the amount of money you used for the ingredients from how much money you make.
