A recent tv add from Walmart show a woman with a bag of groceries; the woman says:"if you spend $100 dollars per week on a bag of groceries like this then you could save $700 per year at Walmart on the same groceries. She then asks what would you do with the $700? The assignment today is to answer the following questions:


1. What would you do with the $700?


2. Why does the woman first say $100 dollars a week and then shift to $700 per year?


3. Use the calculator on the computer to find out how much of a savings $700 is per week.


4. What percent savings would this be?


5. Do you think this add is misleading in anyway?


6. Would you go to Walmart based on this add?
