1. Athena was working on her Girl Scout silver award and was wondering what percentage of people support the Girl Scouts financially through cookie sales outside the grocery store. 8-45 HW eTool (Desmos). Homework Help ✎

2. At the next cookie sale, Athena kept track of how many customers at the grocery store walked by the cookie table and how many stopped to purchase cookies. 32% of families stopped and purchased cookies at the table.

4. 32% 29% 19% 31% 30% 24% 38% 33% 42% 25% 22% 27%
