Math is used every day in the grocery store.  I frequently do calculations to see if I should buy the large size or small size of a product.  I am shocked frequently that buying the large size does NOT save me money.  I wonder why?  The manufacturer must have saved money when they produced the product (on packaging, shipping, etc.)  This keeps me from tying up my money in buying bulk products.
