Answer

14 people

Work Step by Step

To find the number of people who reported an average checking balance of $200 or less, we need to add the number of people who reported an average checking balance from 0 to 100 and from 101 to 200 dollars. Since 5 people reported an average checking balance between 0 and 100 dollars and 9 people reported an average checking balance between 101 and 200 dollars, the total number of people who reported an average checking balance of 200 dollars or less is 14.
