A histogram shows ranges of the number of shoppers per number of stores. The horizontal axis shows number of shoppers ranging from 0 to 1 and then 1 to 13 in increments of 3. The vertical axis ranges from 0 to 5 in increments of 1. The graph shows the following data: 1 to 4 shoppers at 2 stores; 4 to 7 shoppers at 5 stores; 7 to 10 shoppers at 2 stores; 10 to 13 shoppers at 4 stores.

There are a total of 6 stores that had at least 7 shoppers. 5 stores had 4 to 7 shoppers, and 2 stores had 7 to 10 shoppers. So, 5 + 2 = 7 stores had at least 7 shoppers.
