Work Step by Step
We can find this number by finding the sum of the heights of the bars that represent the number of people who have an average monthly balance of 0 to 100 dollars and 101 to 200 dollars.
The heights of these bars are 5 and 9, respectively, so we know that $5+9=14$ people have an average monthly balance of less than 200 dollars.
