Step-by-step explanation:

- The costs for buying any consumer product in bulk vs single items usually differs. This is the strategy used by companies to promote their product to increase their sales.

- The "promotion costs" usually applied to a product in bulk will have less cost per item as compared to any single item that is purchased.

- So it is more cost-effective, assuming that the rate of consumption of the product remains same i.e ( she eats for breakfast almost every day ), to purchase an item in bulk.

- So buying a pack of five would most cost effective for Nancy in the long run. i.e ( monthly or annually, etc ).
