Explanation:

Step1: Identify each bar's value

From the bar graph:

• 1 - 20: ~10 teams (green)
• 21 - 40: ~10 teams (blue)
• 41 - 60: ~50 teams (green)
• 61 - 80: ~10 teams (blue)
• 81 - 100: ~30 teams (green)
• 101 - 120: ~20 teams (blue)

Step2: Sum all values

Total = \(10 + 10 + 50 + 10 + 30 + 20\)
Calculate step - by - step:
\(10+10 = 20\)
\(20 + 50 = 70\)
\(70+10 = 80\)
\(80 + 30 = 110\)
\(110+20 = 130\)

Answer:

130
