Answer

11 people

Work Step by Step

To find the number of people who reported an average checking balance of $301 or more, we need to add the number of people who reported an average checking balance between 301 and 400, between 401 and 500, and 501 or more dollars. Since 6 people reported an average checking balance between 301 and 400 dollars, 2 people reported an average checking balance between 401 and 500 dollars, and 3 people reported an average checking balance of 501 or more dollars, the total number of people who reported an average checking balance of 301 dollars or more is 11.
