This is a powerpoint which will guide the class to determine how Sweet Frog determines their pricing. I went to Sweet Frog and bought 5 different cups of frozen yogurt and made note of the price. The 1st 2 I didn't get a receipt and the second two I did and took a picture of the yogurt on the scale. At the end on the investigation there are questions involving the kids to think about how could I write an equation for this and how could I graph what is going on. Originally I had the questions in a separate document but I attached them to the end of the powerpoint.
