The opening slide describes that the best deal is getting more for your money.  Things on sale are not always at the best price and the amount of product matters.  Students are given five slides with two or three prices.  Students have to determine which is a better deal.  Students may use unit rates, but students are also asked to use another way to determine which is a better deal.  Students can scale up or down using ratio tables or by purchasing the same quantity of each item.
