Answer

16.7%

Work Step by Step

First, we can find the number of people who have an average monthly balance of 201 to 300 dollars by finding the height associated with the bar that represents 201 to 300 dollars. The height of this bar is 5. To find the percentage of people polled who have an average monthly balance of 201 to 300 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%
