The histogram shows the age at which several people started their first job. Using this information, determine how many people started their first job between the ages of 15 and 25.

A histogram is a type of bar graph used to display numerical data that have been organized into equal intervals. So if we’re looking for the number of people who started their job between the ages of 15 and 25, we need to look at two of these bars.

Since the first one goes up to nine, that means nine people started their first job between the ages of 15 and 20. And the second bar means 10 people started their first job between the ages of 20 and 25.

So if we’re trying to find the ages between 15 and 25, we need to add those together. This means 19 people started their first job between the ages of 15 and 25.
