Answer 1

150 people

Explanation:

First, look over the chart and find the rows that have listed as 26 - 30 and 31 - 35.

Find out how high the row goes by looking at the number on the side of the gram.

26 - 30 goes to 60

31 - 35 goes to 90

Then add the 2 numbers together and you will find your total

60 + 90 = 150 people
