#### Work Step by Step

First, we can find the number of people who have an average monthly balance of 0 to 100 dollars by finding the height associated with the bar that represents 0 to 100 dollars. The height of this bar is 5.
To find the percentage of people polled who have an average monthly balance of 0 to 100 dollars, we must divide this number by 30 (which represents the total amount of people polled).
$\frac{5}{30}=\frac{1}{6}\approx$16.7%
