The line graph shows the ages of 120 people. Using the graph, complete the frequency table.

The first point on the line graph shows us that there were 10 people aged five. The second point tells us that there were 30 people aged 10. The third point tells us there were 25 people aged 15. The next point tells us there were 35 people aged 20. And finally, the last point tells us there were 20 people aged 25.

The question already tells us there were 120 people. However, we can check this by adding all the frequencies. 10 plus 30 plus 25 plus 35 plus 20 is equal to 120.

Therefore, the total number of people was 120.
